- 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.
