eZ8 CPU Instruction Classes
eZ8 CPU instructions can be divided functionally into the following groups:
Arithmetic
Bit Manipulation
•
•
•
•
•
•
•
•
Block Transfer
CPU Control
Load
Logical
Program Control
Rotate and Shift
Tables 118 through 125 contain the instructions belonging to each group and the number
of operands required for each instruction. Some instructions appear in more than one table
as these instruction can be considered as a subset of more than one category. Within these
tables, the source operand is identified as ’src’, the destination operand is ’dst’ and a con-
dition code is ’cc’.
