User’s Manual
Examples of Specific Z80 Instructions
After the execution of an instruction that sets a flag, that flag can be used to
control a conditional jump or return instruction. These instructions provide
logical control following the manipulation of single bit, 8-bit byte, or 18-bit
data quantities.
A full set of logical operations, including
CPL
tions between the accumulator and all other 8-bit registers, memory loca-
tions, or immediate operands.
In addition, a full set of arithmetic and logical shifts in both directions are
available which operate on the contents of all 8-bit primary registers or
directly on any memory location. The carry flag can be included or set by
these shift instructions to provide both the testing of shift results and to link
register/register or register/memory shift operations.
Example One:
When a 737-byte data string in memory location DATA must be moved to
location BUFFER, the operation is programmed as follows:
Eleven bytes are required for this operation and each byte of data is moved
in 21 clock cycles.
