Compare Modes (cont’d)
Compare Modes Function
Mode 2
Interrupt-only compare mode;
Only one compare interrupt per timer period is generated
Mode 3
Pin set ‘1’ on match; pin reset ‘0’ on compare timer overflow;
Only one compare event per timer period is generated
Double Register
Mode
Two registers operate on one pin;
Pin toggles on each compare match;
Several compare events per timer period are possible
Single Event Mode Generates single edges or pulses;
Can be used with any compare 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.
