Note 1. The shaded areas are function codes to which expansion instructions are

allocated by default or to which the user can allocate expansion instructions.

Refer to 5-3 Expansion Instructions for more details.

2. Instruction execution times are the same as those for the CPM2A and

CPM2C. Refer to the Programming Manual (W353) for details.
