Table 26

lists the eZ8 CPU instructions, sorted numerically by the Op

Code. The table identifies the addressing modes employed by the instruc-
tion, the effect upon the Flags register, the number of CPU clock cycles
required for the instruction fetch, and the number of CPU clock cycles
required for the instruction execution.
