Notes:

This signal comes from the pin selected by Timer1 PPS register.

TMRx register increments on rising edge.

Synchronize does not operate while in Sleep.

See TxCLK for clock source selections.

See TxGATE for gate source selections.

Synchronized comparator output must not be used in conjunction with synchronized input clock.

20.1

Timer1 Operation

The Timer1 module is a 16-bit incrementing counter accessed through the TMRx register. Writes to TMRx directly

update the counter. When used with an internal clock source, the module is a timer that increments on every

instruction cycle. When used with an external clock source, the module can be used as either a timer or counter and

increments on every selected edge of the external source.

Timer1 is enabled by configuring the ON and GE bits. Table 20-1 shows the possible Timer1 enable selections.
