Section 18 I/O Ports
18.2.5
The GPIO interrupt control register (GPIOIC) is a 16-bit readable/writable register that performs
16-bit interrupt input control.
GPIOIC is initialized to H'00000000 by a power-on reset. It is not initialized by a manual reset or
in standby mode, and retains its contents.
GPIO interrupts are active-low level interrupts. Bit-by-bit masking is possible, and the OR of all
the bits set as GPIO interrupts is used for interrupt detection. Which bits interrupts are input to can
be identified by reading the PDTRA register.
Bit n (n = 0–15)—Port Interrupt Enable (PTIRENn): Specifies whether interrupt input is
performed for each bit.
Bit n: PTIRENn
