Interrupt Status Flag Register
ISF | Interrupt Status Flag 0 (0): Configured interrupt has not been detected. 1 (1): Configured interrupt has been detected. If 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 one is written to the flag. If configured for a level sensitive interrupt and the pin remains asserted then the flag will set again immediately after it is cleared. |
