Section 17 Pin Function Controller (PFC)
PGCRH1 selects the functions of port G pins PG31/RxD2 to PG29/SCK2.
PGCRH1 is initialized to H'0000 by an external power-on reset, but is not initialized by a WDT
reset, in standby mode, or in sleep mode.
Bit 15—Reserved: This bit is always read as 0 and should only be written with 0.
Bit 14—PG31 Mode (PG31MD): Selects the function of the PG31/RxD2 pin.
Bit 14: PG31MD
0
1
Description
General input/output (PG31)
