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.

Bit 7—Enable of

EXIRQ7 Input from P36 (P36IRQ7E): Selects whether or not P36 is used as

the

EXIRQ7 input pin.
