User’s Manual
The
instructions utilize a 16-bit operand and the high order byte is always
pushed first and popped last.
PUSH BC
PUSH DE
PUSH HL
POP HL
The instruction using extended immediate addressing for the source
requires two bytes of data following the Op Code. For example,
LD DE, 0659H
appears as:
In all extended immediate or extended addressing modes, the low order
byte always appears first after the Op Code.
Table 8 lists the 16-bit exchange instructions implemented in the Z80. Op
Code
accumulator flag registers while
between the duplicate set of six general-purpose registers. These Op
Codes are only one byte in length to minimize the time necessary to
perform the exchange so that the duplicate banks can be used to make
very fast interrupt response times.
