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 124 through 131 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’.
