HD404369 Series

Port Mode Register C (PMRC: $025): This register has the following functions (figure 63).

• Prescaler division ratio selection

• Output level control in idle states

Port mode register C (PMRC: $025) is a 4-bit write-only register. It cannot be written during data transfer.

By setting bit 0 (PMRC0) of this register, the prescaler division ratio is selected. Bit 0 (PMRC0) can be

reset to 0 by MCU reset. By setting bit 1 (PMRC1), the output level of the SO pin is controlled in idle

states. The output level changes at the same time that PMRC1 is written to.
