User’s Manual
Instruction Op Codes
except that a displacement is added with indexed addressing. Register
indirect addressing allows for very powerful but simple to implement
memory accesses. The block move and search commands in the Z80 are
extensions of this type of addressing where automatic register
incrementing, decrementing, and comparing has been added. The notation
for indicating register indirect addressing is to put parentheses around the
name of the register that is to be used as the pointer. For example, the
symbol
as a pointer to a memory location. Often register indirect addressing is
used to specify 16-bit operands. In this case, the register contents point to
the lower order portion of the operand while the register contents are
automatically incremented to obtain the upper portion of the operand.
Bit Addressing
The Z80 contains a large number of bit set, reset, and test instructions.
These instructions allow any memory location or CPU register to be
specified for a bit operation through one of three previous addressing
modes (register, register indirect, and indexed) while three bits in the Op
Code specify which of the eight bits is to be manipulated.
Addressing Mode Combinations
Many instructions include more than one operand (such as arithmetic
instructions or loads). In these cases, two types of addressing may be
employed. For example, load can use immediate addressing to specify the
source and register indirect or indexed addressing to specify the
destination.
This section describes each of the Z80 instructions and provides tables
listing the Op Codes for every instruction. In each of these tables, the Op
Codes in shaded areas are identical to those offered in the 8080A CPU.
