The HD64180 will not execute the "undocumented" Z80 instructions, particularly the ones that access the index registers IX and IY as 8-bit halves. The
Hitachi CPU treats them as illegal instructions and accordingly executes the illegal instruction trap, redirecting the PC register to address zero.

The on-chip DMAC makes block memory transfers possible at a rate faster than the LDIR/LDDR instructions. The on-chip generator for wait states makes it possible to access too-slow hardware on a selective basis using a device filter, as is done for the
306:. The most improved instruction group comprises the block instructions; for example those such as LDIR, CPIR, INIR and OTDR. This instruction type takes 21 transition states to execute per iteration; on the HD64180 it takes 14 t-states.
