Functional Description
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
register in response to an external event at the port pin which is associated with this
register. In addition, a specific interrupt request for this capture/compare register is
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
register, specific actions will be taken based on the selected compare mode.
