Z80 ~~~ The 8 bit registers are A, B, C, D, E, H, L, IXL, IXH, IYL, IYH. The 8 bit accu is A. The following addressings modes are available (HL), (IX+n), (IY+n) The following operations are available: MOV r,r MOV r,n MOV A,(nn) MOV (nn),A ADD A,r ADC A,r SUB A,r SBB A,r AND A,r OR A,r XOR A,r CMP A,r INC r DEC r TEST r,(1 << s) The 16 bit registers are BC, DE, HL, IX and IY. The 16 bit accu can be used HL, IX and IY. The following operations are available. MOV rr,nn MOV rr,(nn) MOV (nn),rr ADC aa,rr SBB aa,rr INC rr DEC rr PUSH rr POP rr To my mind the Z80 is a 8 bit processor with many helpful 16 bit stuff. If you know the 6502/10 series (C64), it is much easier to program the Z80 becuase of that. Frank
