CPU Instruction Set Summary

52

An arrow (



indicates assignment of a value. For example:

dst

 dst + src

indicates the source data is added to the destination data and the result is

eZ8 CPU Instruction Classes

eZ8 CPU instructions is divided functionally into the following groups:

Arithmetic

Bit Manipulation

Block Transfer

CPU Control

Load

Logical

Program Control

Rotate and Shift

Table 12

through

Table 19

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 instructions 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
condition code is ‘cc’.
