Section 25 Pin Function Controller (PFC)
25.1.2 Port A Control Registers 1 to 8 (PACR1 to PACR8)
PACR1 to PACR8 are 16-bit readable/writable registers that select the functions of the
multiplexed port A pins. When PINT3B to PINT0B are selected, do not set A input for the same
interrupt.
PACR8 and PACR7 are initialized to H'0000 by a power-on reset or by switching to deep standby
mode. PACR1 to PACR6 are initialized to H'1111 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.
