5.4.3
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:
The output waveform generation from each timer is controlled with the register bits (

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.
