3.3.4 Register to Register Move
Any of the 8-bit registers, A, B, C, D, E, H, and L, can be moved to any other 8-bit regis-
ter, for example:
The alternate 8-bit registers can be a destination, for example:
These instructions are unique to the Rabbit and require 2 bytes and four clocks because of
the required prefix byte. Instructions such as
Several 16-bit register-to-register move instructions are available. Except as noted, these
instructions all require 2 bytes and four clocks. The instructions are listed below.
Other 16-bit register moves can be constructed by using 2-byte moves.
3.3.5 Register Exchanges
Exchange instructions are very powerful because two (or more) moves are accomplished
with one instruction. The following register exchange instructions are implemented.
The following instructions are unique to the Rabbit.
The following special instructions (Rabbit and Z180/Z80) exchange the 16-bit word on
the top of the stack with the HL, the IX, or the IY register. These three instructions are
each 2 bytes and 15 clocks.
