IPINSEL0 is an 8-bit readable/writable register that selects which pins are to be used for interrupt
request input signals (
EXIRQ7 to EXIRQ0) from externally connected modules when operating as
H8S/2214 modules. IPINSEL0 is initialized to H'00 by a power-on reset and in hardware standby
mode. It retains its previous state in a manual reset and in software standby mode.
