Description

GPIO grouped interrupt control register

Fields

INT

Group interrupt status. This bit is cleared by writing a one to it. Writing zero has no effect.

0 (NO_INTERRUPT_REQUEST): No interrupt request is pending.

1 (INTERRUPT_REQUEST_IS): Interrupt request is active.

COMB

Combine enabled inputs for group interrupt

0 (OR_FUNCTIONALITY_A_): OR functionality: A grouped interrupt is generated when any one of the enabled inputs is active (based on its programmed polarity).

1 (AND_FUNCTIONALITY_A): AND functionality: An interrupt is generated when all enabled bits are active (based on their programmed polarity).

TRIG

Group interrupt trigger

0 (EDGE_TRIGGERED): Edge-triggered

1 (LEVEL_TRIGGERED): Level-triggered

RESERVED

Reserved
