18.1
The Timer1/3/5 module is a 16-bit incrementing counter
which is accessed through the TMRxH:TMRxL register
pair. Writes to TMRxH or TMRxL directly update the
counter.
When used with an internal clock source, the module is
a timer and increments on every instruction cycle.
When used with an external clock source, the module
can be used as either a timer or counter and incre-
ments on every selected edge of the external source.
Timer1/3/5 is enabled by configuring the TMRxON and
TMRxGE bits in the TxCON and TxGCON registers,
respectively.

18.2.1
When the internal clock source is selected the
TMRxH:TMRxL register pair will increment on multiples
of F
When the F
Timer1/3/5 register value will increment by four counts
every instruction clock cycle. Due to this condition, a
2 LSB error in resolution will occur when reading the
Timer1/3/5 value. To utilize the full resolution of
Timer1/3/5, an asynchronous input signal must be used
to gate the Timer1/3/5 clock input.
The following asynchronous sources may be used:
• Asynchronous event on the TxG pin to Timer1/3/5
18.2.2
When the external clock source is selected, the
Timer1/3/5 module may work as a timer or a counter.
When enabled to count, Timer1/3/5 is incremented on
the rising edge of the external clock input TxCKI or the
capacitive sensing oscillator signal. Either of these
external clock sources can be synchronized to the
microcontroller
asynchronously.
When used as a timer with a clock oscillator, an
external 32.768 kHz crystal can be used in conjunction
with the dedicated internal oscillator circuit.
