ALARM0

Alarm 0 Value - MODE2

The 32-bit value of ALARM0 is continuously compared with the 32-bit CLOCK value, based on the masking set by MASKn.SEL. When a match occurs, the Alarm 0 interrupt flag in the Interrupt Flag Status and Clear register (INTFLAG.ALARMn) is set on the next counter cycle, and the counter is cleared if CTRL.MATCHCLR is one.
