PD780121, 780122, 780123, and 780124) include mask options. When ordering, it is
possible to select “Power-on-clear (POC) circuit can be used/cannot be used”, “Ring-OSC clock can be
stopped/cannot be stopped by software” and “Pull-up resistor incorporated/not incorporated in 1-bit units (P60 to P63
pins)”.
Flash memory versions corresponding to the mask options of the mask ROM versions are as follows.
