Timer Functionality (Output Compare)
There are two output signals from each timer to generate application-specific waveforms. These waveforms
are generated or altered by comparison results with the timer count value.
There are four comparison results:
?
?
?
?
Counter value reaches zero.
Counter value reaches threshold value of TMR1_TOP or TMR2_TOP register.
Counter value reaches comparison value of TMR1_CMPA or TMR2_CMPA register.
Counter value reaches comparison value of TMR1_CMPB or TMR2_CMPB register.
The output waveform generation from each timer is controlled with the register bits ( TMR_CMPMOD or inverted
with TMR_CMPINV ) in the TMR1_CMPCFGA , TMR1_CMPCFGB , TMR2_CMPCFGA , and TMR2_CMPCFGB registers.
Table 31 summarizes the output waveform generation modes.

Toggle on count = TOP
Set on count = TOP, clear on count = CMPA
Set on count = TOP, clear on count = CMPB
Set to 1
Set on count = CMPA, clear on count = TOP
Toggle on count = CMPA
Set on count = CMPA, clear on count = CMPB
Clear to 0
Set on count = CMPB, clear on count = TOP
Set on count = CMPB, clear on count = CMPA
Toggle on count = CMPB
Toggle on count = ZERO
Set on count = ZERO, clear on count = TOP
Set on count = ZERO, clear on count = CMPA
Set on count = ZERO, clear on count = CMPB
The output signals TMR1OA and TMR1OB from Timer 1, and TMR2OA and TMR2OB from Timer 2, are available
on GPIO. For selecting alternate pin functions, refer to Table 17 and Table 18.
Figure 14 and Figure 15 show examples of all timer output generation modes.
