V2.1, 2003-06

When a capture/compare register has been selected for capture mode, the current

contents of the allocated timer will be latched (‘captured’) into the capture/compare

generated. Either a positive, a negative, or both a positive and a negative external signal

transition at the pin can be selected as the triggering event.

The contents of all registers which have been selected for one of the five compare modes

are continuously compared with the contents of the allocated timers.

When a match occurs between the timer value and the value in a capture/compare
