26.3.1 Timer0 Output
TMR0_out toggles on every match between TMR0L and TMR0H in 8-bit mode or when TMR0H:TMR0L rolls over in 16-bit mode. If the output postscaler is used, the output is scaled by the ratio selected. The Timer0 output can be routed to an I/O pin via the RxyPPS output selection register or internally to a number of Core Independent Peripherals. The Timer0 output can be monitored through software via the OUT output bit.
