Port C Control Register (PCCR)
The port C control register (PCCR) is a 16-bit readable/writable register that selects the functions
of the 5 multiplex pins in port C.
PCCR is initialized to H'0000 by a power-on reset (excluding a WDT power-on reset), and in
hardware standby mode. It is not initialized in software standby mode or sleep mode.
