Section 25 Pin Function Controller (PFC)
25.1.6 Port C Control Registers 1 to 7 (PCCR1 to PCCR7)
PCCR1 to PCCR7 are 16-bit readable/writable registers that select the functions of the
multiplexed port C pins. When IRQ3B to IRQ0B are selected, do not set A input for the same
interrupt.
PCCR2, PCCR5, PCCR6, and PCCR7 are initialized to H'0000 by a power-on reset or by
switching to deep standby mode. PCCR1 is initialized to H'0001 and PCCR3 and PCCR4 are
initialized to the values shown in table 25.9 by a power-on reset or by switching to deep standby
mode. These registers are not initialized either by a manual reset or by switching to sleep mode or
software standby mode.

Description
Reserved
These bits are always read as 0. The write value
should always be 0.
PC25 Mode
These bits control the function of the PC25/IRQ3B/
SDA1 pin.
00: PC25 input (port)
