Section 16 Pin Function Controller (PFC)
16.1.5
PCIORH and PCIORL are 16-bit readable/writable registers that select the input/output directions
of the port C pins. Bits PC20IOR to PC0IOR correspond to pins PC20 to PC00 (the pin name
abbreviations for multiplexed functions are omitted). PCIORH is enabled when a port C pin
functions as a general input/output (PC20 to PC16), otherwise, disabled. PCIORL is enabled when
a port C pin functions as a general input/output (PC15 to PC00), otherwise, disabled.
Setting a bit in PCIORH and PCIORL to 1 makes the corresponding pin function as an output and
clearing a bit in PCIORH and PCIORL to 0 makes the pin function as an input.
Bits 15 to 5 in PCIORH are reserved. These bits are always read as 0. The write value should
always be 0.
The initial values of PCIORH and PCIORL are H'0000.
16.1.6
PCCRH2, PCCRL1, and PCCRL2 are 16-bit readable/writable registers that select the pin
functions for the multiplexed port C pins.
