17. Pin Function Controller (PFC)
17.1.5 Port C I/O Register (PCIOR)
PCIOR is a 16-bit readable/writable register that is used to set the pins on port C as inputs or
outputs. Bits PC15IOR to PC0IOR correspond to pins PC15 to PC0 (names of multiplexed pins
are here given as port names and pin numbers alone). PCIOR is enabled when the port C pins are
functioning as general-purpose inputs/outputs (PC15 to PC0). In other states, PCIOR is disabled.
A given pin on port C will be an output pin if the corresponding bit in PCIOR is set to 1, and an
input pin if the bit is cleared to 0.
The initial value of PCIOR is H'0000.
17.1.6 Port C Control Register (PCCR)
PCCR is a 16-bit readable/writable register that is used to select the multiplexed pin function of
the pins on port C.
