Compare Modes
Mode 2
Mode 3
Double Register
Mode
Single Event Mode
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 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 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 compare mode selected.
