* History:
* 990314 HJB
* The disassembler knows about valid opcodes for M6800/1/2/3/8 and HD63701.
* 990302 HJB
* Changed the string array into a table of opcode names (or tokens) and
* argument types. This second try should give somewhat better results.
* Named the undocumented HD63701YO opcodes $12 and $13 'asx1' and 'asx2',
* since 'add contents of stack to x register' is what they do.

- Verify invalid opcodes for the different CPU types.
- A lot more work and cleanups, especially for the 6801 derivatives.
History
991031 ZV
Added NSC-8105 support
990319 HJB
Fixed wrong LSB/MSB order for push/pull word.
Subtract .extra_cycles at the beginning/end of the exectution loops.
990316 HJB
Renamed to 6800, since that's the basic CPU.
Added different cycle count tables for M6800/2/8, M6801/3 and m68xx.
990314 HJB
Also added the M6800 subtype.
990311 HJB
Added _info functions. Now uses static m6808_Regs struct instead
of single statics. Changed the 16 bit registers to use the generic
PAIR union. Registers defined using macros. Split the core into
four execution loops for M6802, M6803, M6808 and HD63701.
TST, TSTA and TSTB opcodes reset carry flag.
990301 HJB
Modified the interrupt handling. No more pending interrupt checks.
WAI opcode saves state, when an interrupt is taken (IRQ or OCI),
the state is only saved if not already done by WAI.
