Z80 CPU
User’s Manual
conditions, or data packed into memory locations, making memory
utilization more efficient.
The Z80 can set, reset, or test any bit in the accumulator, any general-
purpose register or any memory location with a single instruction.
Table 15 lists the 240 instructions that are available for this purpose.
Register addressing can specify the accumulator or any general-purpose
register on which the operation is to be performed. Register indirect and
indexed addressing are available to operate on external memory locations.
Bit test operations set the Zero flag (Z) if the tested bit is a zero.
Jump, Call, and Return
Table 16 lists all the jump, call, and return instructions implemented in the
Z80 CPU. A jump is a branch in a program where the program counter is
loaded with the 16-bit value as specified by one of the three available
addressing modes (Immediate Extended, Relative, or Register Indirect).
Notice that the jump group has several conditions that can be specified
before the jump is made. If these conditions are not met, the program
merely continues with the next sequential instruction. The conditions are
all dependent on the data in the flag register. The immediate extended
addressing is used to jump to any location in the memory. This instruction
requires three bytes (two to specify the 16-bit address) with the low order
address byte first, followed by the high order address byte.
For example, an unconditional jump to memory location
The relative jump instruction uses only two bytes, the second byte is a
signed two’s complement displacement from the existing PC. This
displacement can be in the range of +129 to -126 and is measured from
the address of the instruction Op Code.
