18.3.8 Port C Control Register (PCCR)
PCCR is a 16-bit read/write register that selects the functions for the sixteen port C multiplexed
pins. There are instances when these register settings will be ignored, depending on the operation
mode. Refer to table 18.2, Pin Arrangement by Mode, for details.
PCCR is initialized to H'0000 by power-on resets but is not initialized for manual resets, reset by
WDT, standby mode, or sleep mode, so the previous data is maintained.
