23.1.7 Port C I/O Register L (PCIORL)
PCIORL 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 respectively (multiplexed port
pin names except for the port names are abbreviated here). PCIORL is enabled when the port C
pins are functioning as general-purpose inputs/outputs (PC15 to PC0). In other states, PCIORL is
disabled. A given pin on port C will be an output pin if the corresponding bit in PCIORL is set to
1, and an input pin if the bit is cleared to 0.
The initial value of PCIORL is H'0000.
