25.2.3 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. The PC14IOR to PC0IOR bits correspond to the PC14/WAIT to PC0/A0/CS7 pins,
respectively. PCIORL is enabled when the port C pins are functioning as general-purpose
inputs/outputs (PC14 to PC0). In other states, PCIORL is disabled. If a bit in PCIORL is set to 1,
the corresponding pin on port C functions as an output pin. If it is cleared to 0, the corresponding
pin functions as an input pin.
Bit 15 of PCIORL is reserved. This bit is always read as 0. The write value should always be 0.
