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. - *****************************************************************************/ /* |
