Section 16 Pin Function Controller (PFC)
16.3.5
The port C IO register (PCIOR) is a 16-bit readable/writable register that selects the input/output
direction of the 15 pins in port C. Bits PC14IOR to PC0IOR correspond to pins PC14/TOH10 to
PC0/WRL. PCIOR is enabled when port C pins function as general input/output pins (PC14 to
PC0), and disabled otherwise.
When port C pins function as PC14 to PC0, 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'8000 by a power-on reset (excluding a WDT power-on reset), and in
hardware standby mode. It is not initialized in software standby mode or sleep mode.
16.3.6
Port C control registers 1 and 2 (PCCR1, PCCR2) are 16-bit readable/writable registers that select
the functions of the 15 multiplex pins in port C. PCCR1 selects the functions of the pins for the
upper 7 bits in port C, and PCCR2 selects the functions of the pins for the lower 8 bits in port C.
PCCR1 and PCCR2 are initialized to H'C000 and H'0BFF, respectively, by a power-on reset
(excluding a WDT power-on reset), and in hardware standby mode. They are not initialized in
software standby mode or sleep mode.
