Programmable Reference Analog Comparator (PRACMP)

Interrupts
If the bus clock is available when a valid edge defined in ACINTS[1:0] occurs, the ACMPF bit in
PRACMPxCS register is asserted. If ACIEN is set, a PRACMP interrupt event occurs. The ACMPF bit
remains asserted until the PRACMP interrupt is cleared by software. When in stop3 mode, a valid edge on
ACMP output generates an asynchronous interrupt which can wake the MCU up from stop3. The interrupt
can be cleared by writing a 0 to the ACMPF bit.
