Notes 1. The
µPD78F0134 does not support the µPD780136 and 780138.
2. The internal flash memory, internal high-speed RAM capacities, and internal expansion RAM
capacities can be changed using the internal memory size switching register (IMS) and the internal
expansion RAM size switching register (IXS).
