32.2.9 Port C I/O Register 0 (PCIOR0)
PCIOR0 is a 16-bit readable/writable register that is used to set the pins on port C as inputs or
outputs. The PC10IOR to PC0IOR bits correspond to the PC10 to PC0 pins, respectively.
PCIOR0 is enabled when the port C pins are functioning as general-purpose I/O (PC10 to PC0) or
TIOC I/O of multi-function timer pulse unit 2. In other states, PCIOR0 is disabled. If a bit in
PCIOR0 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.
Bits 15 to 11 in PCIOR0, and bits 10 and 9 in PCIOR0 in the SH7262 Group are reserved. These
bits are always read as 0. The write value should always be 0.
