Clearing the INTOUTn line from a GPIO cell

Last Updated: January 01, 2012

If I have an interrupt on edge, what clears the Interrupt Output (INTO) line from the GPIO cell?


With an interrupt on edge, the INTO line will continue to hold low until the pin interrupt enable is cleared, the voltage at the pins transitions to the opposite state, or the interrupt mode is changed so that current pin state does not create an interrupt. More information on GPIO interrupts can be found in section 6.1.4 'GPIO Block Interrupts' of the Technical Reference Manual (TRM).
