Z80 CPU
User’s Manual
Addressing Modes
Most of the Z80 instructions operate on data stored in internal CPU
registers, external memory, or in the I/O ports. Addressing refers to how
the address of this data is generated in each instruction. This section is a
brief summary of the types of addressing used in the Z80 while
subsequent sections detail the type of addressing available for each
instruction group.
Immediate
In this mode of addressing, the byte following the Op Code in memory
contains the actual operand.
Examples of this type of instruction is loading the accumulator with a
constant, where the constant is the byte immediately following the Op
Code.
Immediate Extended
This mode is an extension of immediate addressing in that the two bytes
following the Op Codes are the operand.
Examples of this type of instruction is loading the HL register pair (16-bit
register) with 16 bits (two bytes) of data.
