18.3.2 Timer0 Output
TMR0_out is the output of the postscaler. 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.
Important: When Timer0 is in 8-bit mode and TMR0H = 0,
TMR0_out remains high.
The Timer0 output can be routed to an I/O pin via the RxyPPS output selection register. The Timer0 output can be monitored through software via the T0OUT output bit.
