This example indicates that the source data is added to the destination data; the result is
stored in the destination location.
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 105 through 112 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 condi-
tion code is cc.
