CMP Analog comparator interrupt AC output is toggling as configured by INTMODE in ACn.INTCTRL

When an interrupt condition occurs, the corresponding interrupt flag is set in the Status (ACn.STATUS) register.

An interrupt source is enabled or disabled by writing to the corresponding bit in the peripheral’s Interrupt Control (ACn.INTCTRL) register.

The AC can generate a comparator interrupt, CMP, and can request this interrupt on either rising, falling, or both edges of the toggling comparator output. This is configured by writing to the Interrupt Mode (INTMODE) bit field in the Interrupt Control (ACn.INTCTRL) register. The interrupt is enabled by writing a ‘1’ to the Analog Comparator Interrupt Enable (CMP) bit in the Interrupt Control (ACn.INTCTRL) register. The interrupt request remains active until the interrupt flag is cleared. Refer to the Status (ACn.STATUS) register description for details on how to clear the interrupt flags.
