22. Pin Function Controller (PFC)
PBIR is initialized to H'0000 by a power-on reset (excluding a WDT power-on reset), in hardware standby mode, and in
software standby mode. It is not initialized in sleep mode.

The port C IO register (PCIOR) is a 16-bit readable/writable register that selects the input/output direction of the five pins
in port C. Bits PC4IOR to PC0IOR correspond to pins PC4/IRQ0 to PC0/TxD1. PCIOR is enabled when port C pins
function as general input/output pins (PC4 to PC0 or transmit/receive input/output for the SSU* (SSI1 and SSO1)), and
disabled otherwise.
When port C pins function as PC4 to PC0 or transmit/receive input/output for the SSU* (SSI1 and SSO1), a pin becomes
an output when the corresponding bit in PCIOR is set to 1, and an input when the bit is cleared to 0.
PCIOR is initialized to H'0000 by a power-on reset (excluding a WDT power-on reset), in hardware standby mode, and in
software standby mode. It is not initialized in sleep mode.
