+EXAMPLE:\r
+-------\r
+As an example, I'll build an imaginary hardware platform.\r
+\r
+\r
+The system is fairly simple, comprising a 68000, an input device, an output\r
+device, a non-maskable-interrupt device, and an interrupt controller.\r
+\r
+\r
+The input device receives input from the user and asserts its interrupt\r
+request line until its value is read. Reading from the input device's\r
+memory-mapped port will both clear its interrupt request and read an ASCII\r
+representation (8 bits) of what the user entered.\r
+\r
+The output device reads value when it is selected through its memory-mapped\r
+port and outputs it to a display. The value it reads will be interpreted as\r
+an ASCII value and output to the display. The output device is fairly slow\r
+(it can only process 1 byte per second), and so it asserts its interrupt\r
+request line when it is ready to receive a byte. Writing to the output device\r
+sends a byte to it. If the output device is not ready, the write is ignored.\r
+Reading from the output device returns 0 and clears its interrupt request line\r
+until another byte is written to it and 1 second elapses.\r
+\r
+The non-maskable-interrupt (NMI) device, as can be surmised from the name,\r
+generates a non-maskable-interrupt. This is connected to some kind of external\r
+switch that the user can push to generate a NMI.\r
+\r
+Since there are 3 devices interrupting the CPU, an interrupt controller is\r
+needed. The interrupt controller takes 7 inputs and encodes the highest\r
+priority asserted line on the 3 output pins. the input device is wired to IN2\r
+and the output device is wired to IN1 on the controller. The NMI device is\r
+wired to IN7 and all the other inputs are wired low.\r
+\r
+The bus is also connected to a 1K ROM and a 256 byte RAM.\r
+Beware: This platform places ROM and RAM in the same address range and uses\r
+ the FC pins to select the correct address space!\r
+ (You didn't expect me to make it easy, did you? =)\r

+\r
+Compiling the example host environment:\r
+--------------------------------------\r
+\r
+I've only put in an os-dependant portion for dos/windows, so you'll either\r
+have to compile for that system or make your own osd code based on osd_dos.c\r
+and modify the makefile accordingly.\r
+\r
+I compiled this example using the compiler from mingw (www.mingw.org) but you\r
+could also use djgpp (www.delorie.com).\r
+\r
+- Copy the m68k files to a directory. Then extract the files from example.zip to\r
+ the same directory, overwriting m68kconf.h. program.bin is the actual 68000\r
+ program you will be running.\r
+- Make your own osd_get_key() in the same fashion as in osd_dos.c if you're not\r
+ compiling for dos/windows.\r
+- Type make\r
+- Perform the necessary animal sacrifices.\r
+- Type sim program.bin\r
+\r
+\r
+Keys:\r
+ ESC - quits the simulator\r
+ ~ - generates an NMI interrupt\r
+ Any other key - Genearate input for the input device\r
+\r
+\r
+Note: I've cheated a bit in the emulation. There is no speed control\r
+ to set the speed the CPU runs at; it simply runs as fast as your\r
+ processor can run it.\r
+ To add speed control, you will need a high-precision timestamp\r
+ function (like the RDTSC instruction for newer Pentium CPUs)\r
+ and a bit of arithmetic to make the cycles argument for m68k_execute().\r
+ I'll leave that as an excercise to the reader.\r

+The history of Musashi for anyone who might be interested:
+---------------------------------------------------------
+
+Musashi was born out of sheer boredom.
+I needed something to code, and so having had fun with a few of the emulators
+around, I decided to try my hand at CPU emulation.
+I had owned an Amiga for many years and had done some assembly coding on it so
+I figured it would be the ideal chip to cut my teeth on.
+Had I known then how much work was involved in emulating a chip like this, I
+may not have even started ;-)
+
+
+15-Jul-2013: Musashi license changed to MIT.
+
+10-Jun-2002: Musashi 3.4 released
+ - Added various undocumented m68k features thanks to Bart
+ Trzynadlowski's experiments.
+ See http://dynarec.com/~bart/files/68knotes.txt for details.
+ - Fixed a bug that caused privilege violation and illegal
+ instruction exceptions to stack the wrong PC value.
+ - Added emulation of address errors (Note: this only works
+ in 68000 mode. All other CPUs require a LOT of overhead
+ to emulate this. I'm not sure if I'll implement them or not.
+
+27-Jan-2001: Musashi 3.3 released
+ - Fixed problem when displaying negative numbers in disassembler
+ - Fixed cpu type selector - was allowing 020 instructions to be
+ disassembled when in 000 mode.
+ - Fixed opcode jumptable generator (ambiguous operators in the
+ test for f-line ops)
+ - Fixed signed/unsigned problem in divl and mull opcodes (not
+ sure if this was causing an error but best to be sure)
+ - Cleaned up the naming scheme for the opcode handlers
+
+14-Aug-2000: Musashi 3.2 released
+ - Fixed RTE bug that killed the program counter when in m68020
+ mode.
+ - Minor fixes in negx and nbcd.
+ - renamed d68k.c to m68kdasm.c and merged d68k.h into m68k.h.
+ d68k_read_xxx() instructions have been renamed to
+ m68k_read_xxx_disassembler().
+ - Rewrote exception processing and fixed 68020 stack frame
+ problems.
+ - FINALLY fixed the mull and divl instructions.
+ - Added 64-bit safe code fixes.
+ - Added 64-bit optimizations (these will only be ANSI compliant
+ under c9x, and so to use them you must turn on M68K_USE_64_BIT
+ in m68kconf.h).
+
+28-May-2000: Musashi 3.1 released
+ - Fixed bug in m68k_get_reg() that retrieved the wrong value for
+ the status register.
+ - Fixed register bug in movec.
+ - Fixed cpu type comparison problem that caused indexed
+ addressing modes to be incorrectly interpreted when in m68ec020
+ mode.
+ - Added code to speed up busy waiting on some branch instructions.
+ - Fixed some bfxxx opcode bugs.
+
+05-Apr-2000: Musashi 3.0 released
+ - Major code overhaul.
+ - Rewrote code generator program and changed the format of
+ m68k_in.c.
+ - Added support for m68ec020.
+ - Removed timing from the opcode handlers.
+ - Added correct timing for m68000, m68010, and m68020.
+ Note: 68020 timing is the cache timing from the manual.
+ - Removed the m68k_peek_xxx() and m68k_poke_xxx() instructions and
+ replaced them with m68k_get_reg() and m68k_set_reg().
+ - Added support for function codes.
+ - Revamped m68kconf.h to be easier to configure and more powerful.
+ - Added option to separate immediate and normal reads.
+ - Added support for (undocumented) m68000 instruction prefetch.
+ - Rewrote indexed addressing mode handling.
+ - Rewrote interrupt handling.
+ - Fixed a masking bug for m68k_get_reg() when requesting the PC.
+ - Moved the instruction table sorting routine to m68kmake.c so
+ that it is invoked at compile time rather than at runtime.
+ - Rewrote the exception handling routines to support different
+ stack frames (needed for m68020 emulation).
+ - Rewrote faster status register and condition code flag handling
+ functions / macros.
+ - Fixed function code handling to fetch from program space when
+ using pc-relative addressing.
+ - Fixed initial program counter and stack pointer fetching on
+ reset (loads from program space now).
+ - A lot of code cleanup.
+ - LOTS of bugfixes (especially in the m68020 code).
+
+13-May-1999: Musashi 2.2 released
+ - Added support for m68020.
+ - Lots of bugfixes.
+
+25-Mar-1999: Musashi 2.1 released
+ - Added support for m68010.
+ - Many bugfixes.
+
+17-Mar-1999: Musashi 2.0 released
+ - Major code overhaul.
+ - Replaced monolithic codebase with a code generator program.
+ - Added correct m68000 timing.
+ - Moved timing into the opcode handlers.
+
+06-Jan-1999: Musashi 1.0 released
+
+20-Dec-1998: Beta release of Musashi v0.5 that could run Rastan Saga under MAME
+ (barely).

+/* Input file for m68kmake
+ * -----------------------
+ *
+ * All sections begin with 80 X's in a row followed by an end-of-line
+ * sequence.
+ * After this, m68kmake will expect to find one of the following section
+ * identifiers:
+ * M68KMAKE_PROTOTYPE_HEADER - header for opcode handler prototypes
+ * M68KMAKE_PROTOTYPE_FOOTER - footer for opcode handler prototypes
+ * M68KMAKE_TABLE_HEADER - header for opcode handler jumptable
+ * M68KMAKE_TABLE_FOOTER - footer for opcode handler jumptable
+ * M68KMAKE_TABLE_BODY - the table itself
+ * M68KMAKE_OPCODE_HANDLER_HEADER - header for opcode handler implementation
+ * M68KMAKE_OPCODE_HANDLER_FOOTER - footer for opcode handler implementation
+ * M68KMAKE_OPCODE_HANDLER_BODY - body section for opcode handler implementation
+ *
+ * NOTE: M68KMAKE_OPCODE_HANDLER_BODY must be last in the file and
+ * M68KMAKE_TABLE_BODY must be second last in the file.
+ *
+ * The M68KMAKE_OPHANDLER_BODY section contains the opcode handler
+ * primitives themselves. Each opcode handler begins with:
+ * M68KMAKE_OP(A, B, C, D)
+ *
+ * where A is the opcode handler name, B is the size of the operation,
+ * C denotes any special processing mode, and D denotes a specific
+ * addressing mode.
+ * For C and D where nothing is specified, use "."
+ *
+ * Example:
+ * M68KMAKE_OP(abcd, 8, rr, .) abcd, size 8, register to register, default EA
+ * M68KMAKE_OP(abcd, 8, mm, ax7) abcd, size 8, memory to memory, register X is A7
+ * M68KMAKE_OP(tst, 16, ., pcix) tst, size 16, PCIX addressing
+ *
+ * All opcode handler primitives end with a closing curly brace "}" at column 1
+ *
+ * NOTE: Do not place a M68KMAKE_OP() directive inside the opcode handler,
+ * and do not put a closing curly brace at column 1 unless it is
+ * marking the end of the handler!
+ *
+ * Inside the handler, m68kmake will recognize M68KMAKE_GET_OPER_xx_xx,
+ * M68KMAKE_GET_EA_xx_xx, and M68KMAKE_CC directives, and create multiple
+ * opcode handlers to handle variations in the opcode handler.
+ * Note: M68KMAKE_CC will only be interpreted in condition code opcodes.
+ * As well, M68KMAKE_GET_EA_xx_xx and M68KMAKE_GET_OPER_xx_xx will only
+ * be interpreted on instructions where the corresponding table entry
+ * specifies multiple effective addressing modes.
+ * Example:
+ * clr 32 . . 0100001010...... A+-DXWL... U U U 12 6 4
+ *
+ * This table entry says that the clr.l opcde has 7 variations (A+-DXWL).
+ * It is run in user or supervisor mode for all CPUs, and uses 12 cycles for
+ * 68000, 6 cycles for 68010, and 4 cycles for 68020.

+ * This is the code generator program which will generate the opcode table

+ *
+ * It requires an input file to function (default m68k_in.c), but you can
+ * specify your own like so:
+ *
+ * m68kmake <output path> <input file>
+ *
+ * where output path is the path where the output files should be placed, and
+ * input file is the file to use for input.
+ *
+ * If you modify the input file greatly from its released form, you may have
+ * to tweak the configuration section a bit since I'm using static allocation
+ * to keep things simple.
+ *

+ * TODO: - build a better code generator for the move instruction.
+ * - Add callm and rtm instructions
+ * - Fix RTE to handle other format words
+ * - Add address error (and bus error?) handling

+INTRODUCTION:
+------------
+
+Musashi is a Motorola 68000, 68010, 68EC020, and 68020 emulator written in C.
+This emulator was written with two goals in mind: portability and speed.
+
+The emulator is written to ANSI C89 specifications. It also uses inline
+functions, which are C9X compliant.
+
+It has been successfully running in the MAME project (www.mame.net) for years
+and so has had time to mature.

+
+
+BASIC CONFIGURATION:
+-------------------
+The basic configuration will give you a standard 68000 that has sufficient
+functionality to work in a primitive environment.
+
+This setup assumes that you only have 1 device interrupting it, that the
+device will always request an autovectored interrupt, and it will always clear
+the interrupt before the interrupt service routine finishes (but could
+possibly re-assert the interrupt).
+You will have only one address space, no tracing, and no instruction prefetch.
+
+To implement the basic configuration:
+
+- Open m68kconf.h and verify that the settings for INLINE will work with your
+ compiler. (Currently set to "static __inline__", which works in gcc 2.9.
+ For C9X compliance, it should be "inline")
+
+- In your host program, implement the following functions:
+ unsigned int m68k_read_memory_8(unsigned int address);
+ unsigned int m68k_read_memory_16(unsigned int address);
+ unsigned int m68k_read_memory_32(unsigned int address);
+ void m68k_write_memory_8(unsigned int address, unsigned int value);
+ void m68k_write_memory_16(unsigned int address, unsigned int value);
+ void m68k_write_memory_32(unsigned int address, unsigned int value);
+
+- In your host program, be sure to call m68k_pulse_reset() once before calling
+ any of the other functions as this initializes the core.
+
+- Use m68k_execute() to execute instructions and m68k_set_irq() to cause an
+ interrupt.
+
+
+
+ADDING PROPER INTERRUPT HANDLING:
+--------------------------------
+The interrupt handling in the basic configuration doesn't emulate the
+interrupt acknowledge phase of the CPU and automatically clears an interrupt
+request during interrupt processing.
+While this works for most systems, you may need more accurate interrupt
+handling.
+
+To add proper interrupt handling:
+
+- In m68kconf.h, set M68K_EMULATE_INT_ACK to OPT_SPECIFY_HANDLER
+
+- In m68kconf.h, set M68K_INT_ACK_CALLBACK(A) to your interrupt acknowledge
+ routine
+
+- Your interrupt acknowledge routine must return an interrupt vector,
+ M68K_INT_ACK_AUTOVECTOR, or M68K_INT_ACK_SPURIOUS. most m68k
+ implementations just use autovectored interrupts.
+
+- When the interrupting device is satisfied, you must call m68k_set_irq(0) to
+ remove the interrupt request.
+
+
+
+MULTIPLE INTERRUPTS:
+-------------------
+The above system will work if you have only one device interrupting the CPU,
+but if you have more than one device, you must do a bit more.
+
+To add multiple interrupts:
+
+- You must make an interrupt arbitration device that will take the highest
+ priority interrupt and encode it onto the IRQ pins on the CPU.
+
+- The interrupt arbitration device should use m68k_set_irq() to set the
+ highest pending interrupt, or 0 for no interrupts pending.
+
+
+
+SEPARATE IMMEDIATE READS:
+------------------------
+You can write faster memory access functions if you know whether you are
+fetching from ROM or RAM. Immediate reads are always from the program space
+(Always in ROM unless it is running self-modifying code).
+
+To enable separate immediate reads:
+
+- In m68kconf.h, turn on M68K_SEPARATE_READ_IMM.
+
+- In your host program, implement the following functions:
+ unsigned int m68k_read_immediate_16(unsigned int address);
+ unsigned int m68k_read_immediate_32(unsigned int address);
+
+- If you need to know the current PC (for banking and such), set
+ M68K_MONITOR_PC to OPT_SPECIFY_HANDLER, and set M68K_SET_PC_CALLBACK(A) to
+ your routine.
+
+
+
+ADDRESS SPACES:
+--------------
+Most systems will only implement one address space, placing ROM at the lower
+addresses and RAM at the higher. However, there is the possibility that a
+system will implement ROM and RAM in the same address range, but in different
+address spaces.
+
+In this case, you might get away with assuming that immediate reads are in the
+program space and all other reads are in the data space, if it weren't for the
+fact that the exception vectors are fetched from the data space. As a result,
+anyone implementing this kind of system will have to copy the vector table
+from ROM to RAM using pc-relative instructions.
+
+This makes things bad for emulation, because this means that a non-immediate
+read is not necessarily in the data space.
+The m68k deals with this by encoding the requested address space on the
+function code pins:
+
+ FC
+ Address Space 210
+ ------------------ ---
+ USER DATA 001
+ USER PROGRAM 010
+ SUPERVISOR DATA 101
+ SUPERVISOR PROGRAM 110
+ CPU SPACE 111 <-- not emulated in this core since we emulate
+ interrupt acknowledge in another way.
+
+To emulate the function code pins:
+
+- In m68kconf.h, set M68K_EMULATE_FC to OPT_SPECIFY_HANDLER and set
+ M68K_SET_FC_CALLBACK(A) to your function code handler function.
+
+- Your function code handler should select the proper address space for
+ subsequent calls to m68k_read_xx (and m68k_write_xx for 68010+).
+
+Note: immediate reads are always done from program space, so technically you
+ don't need to implement the separate immediate reads, although you could
+ gain more speed improvements leaving them in and doing some clever
+ programming.
+
+
+
+USING DIFFERENT CPU TYPES:
+-------------------------
+The default is to enable only the 68000 cpu type. To change this, change the
+settings for M68K_EMULATE_010 etc in m68kconf.h.
+
+To set the CPU type you want to use:
+
+- Make sure it is enabled in m68kconf.h. Current switches are:
+ M68K_EMULATE_010
+ M68K_EMULATE_EC020
+ M68K_EMULATE_020
+
+- In your host program, call m68k_set_cpu_type() and then call
+ m68k_pulse_reset(). Valid CPU types are:
+ M68K_CPU_TYPE_68000,
+ M68K_CPU_TYPE_68010,
+ M68K_CPU_TYPE_68EC020,
+ M68K_CPU_TYPE_68020
+
+
+
+CLOCK FREQUENCY:
+---------------
+In order to emulate the correct clock frequency, you will have to calculate
+how long it takes the emulation to execute a certain number of "cycles" and
+vary your calls to m68k_execute() accordingly.
+As well, it is a good idea to take away the CPU's timeslice when it writes to
+a memory-mapped port in order to give the device it wrote to a chance to
+react.
+
+You can use the functions m68k_cycles_run(), m68k_cycles_remaining(),
+m68k_modify_timeslice(), and m68k_end_timeslice() to do this.
+Try to use large cycle values in your calls to m68k_execute() since it will
+increase throughput. You can always take away the timeslice later.
+
+
+
+MORE CORRECT EMULATION:
+----------------------
+You may need to enable these in order to properly emulate some of the more
+obscure functions of the m68k:
+
+- M68K_EMULATE_BKPT_ACK causes the CPU to call a breakpoint handler on a BKPT
+ instruction
+
+- M68K_EMULATE_TRACE causes the CPU to generate trace exceptions when the
+ trace bits are set
+
+- M68K_EMULATE_RESET causes the CPU to call a reset handler on a RESET
+ instruction.
+
+- M68K_EMULATE_PREFETCH emulates the 4-word instruction prefetch that is part
+ of the 68000/68010 (needed for Amiga emulation).
+ NOTE: if the CPU fetches a word or longword at an odd address when this
+ option is on, it will yield unpredictable results, which is why a real
+ 68000 will generate an address error exception.
+
+- M68K_EMULATE_ADDRESS_ERROR will cause the CPU to generate address error
+ exceptions if it attempts to read a word or longword at an odd address.
+
+- call m68k_pulse_halt() to emulate the HALT pin.
+
+
+
+CONVENIENCE FUNCTIONS:
+---------------------
+These are in here for programmer convenience:
+
+- M68K_INSTRUCTION_HOOK lets you call a handler before each instruction.
+
+- M68K_LOG_ENABLE and M68K_LOG_1010_1111 lets you log illegal and A/F-line
+ instructions.
+
+
+
+MULTIPLE CPU EMULATION:
+----------------------
+The default is to use only one CPU. To use more than one CPU in this core,
+there are some things to keep in mind:
+
+- To have different cpus call different functions, use OPT_ON instead of
+ OPT_SPECIFY_HANDLER, and use the m68k_set_xxx_callback() functions to set
+ your callback handlers on a per-cpu basis.
+
+- Be sure to call set_cpu_type() for each CPU you use.
+
+- Use m68k_set_context() and m68k_get_context() to switch to another CPU.
+
+
+
+LOAD AND SAVE CPU CONTEXTS FROM DISK:
+------------------------------------
+You can use them68k_load_context() and m68k_save_context() functions to load
+and save the CPU state to disk.
+
+
+
+GET/SET INFORMATION FROM THE CPU:
+--------------------------------
+You can use m68k_get_reg() and m68k_set_reg() to gain access to the internals
+of the CPU.
+
