Notes:
Instructions in Italic face are Z380 new instructions, instructions with underline are Z180 original instructions.
L1: In Long Word mode, this instruction loads in 32 bits; dst(31-0) ← src(31-0)
L9: In Long Word mode, this instruction operates in 32-bits; If A(7) = 0 then HL(31-16) = 0000h else FFFFh
@: Converts accumulator content into packed BCD following add or subtract with packed BCD operands.
#: Interrupts are not sampled at the end of EI and DI.
