Analog Comparator (AC)
An interrupt source is enabled or disabled by writing to the corresponding bit in the peripheral's Interrupt
Control register (ACn.INTCTRL).
An interrupt request is generated when the corresponding interrupt source is enabled and the Interrupt
Flag is set. The interrupt request remains active until the Interrupt Flag is cleared. See the ACn.STATUS
register description for details on how to clear Interrupt Flags.
27.3.5 Sleep Mode Operation
In Idle sleep mode, the AC will continue to operate as normal.
In Standby sleep mode, the AC is disabled by default. If the Run in Standby Sleep Mode bit
(RUNSTDBY) in the Control A register (ACn.CTRLA) is written to '1', the AC will continue to operate as
normal with Event, Interrupt, and AC output on pad even if the CLK_PER is not running in Standby sleep
mode.
In Power Down sleep mode, the AC and the output to the pad are disabled.
