Description

Interrupt Status Flag Register

Fields

ISF

Interrupt Status Flag

0 (0): Configured interrupt is not detected.

1 (1): Configured interrupt is detected. If the pin is configured to generate a DMA request, then the corresponding flag will be cleared automatically at the completion of the requested DMA transfer. Otherwise, the flag remains set until a logic 1 is written to the flag. If the pin is configured for a level sensitive interrupt and the pin remains asserted, then the flag is set again immediately after it is cleared.
