DESCRIPTION

R16405

(4015h)

Interrupt Status

15:0

GPn_EINT

GPIO interrupt.

(Trigger is controlled by

GPn_INT_MODE)

Note: Cleared when a ‘1’ is written.

R16413

(401Dh)

Interrupt Status

5 Mask

15:0

IM_GPn_EINT

Interrupt mask.

0 = Do not mask interrupt.

1 = Mask interrupt.

Default value is 1 (masked)

Note: n is a number between 1 and 16 that identifies the individual GPIO.

23.2.4 ON PIN INTERRUPTS

The primary ON_PIN_INT interrupt comprises a single secondary interrupt as described in

Section 11.6. The secondary interrupt bit is defined in Table 94.

The secondary interrupt can be masked. When the mask bit is set, the corresponding interrupt event

is masked and does not trigger an ON_PIN_INT interrupt. The secondary interrupt bit in R16401

(4011h) is valid regardless of whether the mask bit is set. The secondary interrupt is masked by

default.

Interrupt Status

ON_PIN_CINT

ON pin interrupt.

(Rising and Falling Edge triggered)

Note: Cleared when a ‘1’ is written.

R16409

(4019h)

Interrupt Status

1 Mask

IM_ON_PIN_CINT

Interrupt mask.

0 = Do not mask interrupt.

1 = Mask interrupt.

Default value is 1 (masked)

23.2.5 WATCHDOG INTERRUPTS

The primary WDOG_INT interrupt comprises a single secondary interrupt as described in Section 25.

The secondary interrupt bits are defined in Table 95.

The secondary interrupt can be masked. When the mask bit is set, the corresponding interrupt event

is masked and does not trigger a WDOG_INT interrupt. The secondary interrupt bit in R16401

(4011h) is valid regardless of whether the mask bit is set. The secondary interrupt is masked by

default.
