27.5. eZ8 CPU Instruction Summary
Table 186 summarizes the eZ8 CPU instructions. The table identifies the addressing
modes employed by the instruction, 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.
