13.1
The Timer1 and Timer3 modules are 16-bit increment-
ing counters which are 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 is enabled by configuring the TMRxON and
TMRxGE bits in the TxCON and TxGCON registers,
respectively. Table 13-2 displays the Timer1/3 enable
selections.

13.2
The TMRxCS<1:0> bits of the TxCON register and the
T1OSCEN bit of the T1CON register are used to select
the clock source for Timer1/3. Table 13-3 displays the
clock source selections.
13.2.1
When the internal clock source is selected, the
TMRxH:TMRxL register pair will increment on multiples
of F
13.2.2
When the external clock source is selected, the
Timer1/3 modules may work as a timer or a counter.
When enabled to count, Timer1/3 is incremented on the
rising edge of the external clock input TxCKI or a
capacitive sensing oscillator signal. Either of these
external clock sources can be synchronized to the
microcontroller system clock or they can be run
asynchronously. If set for the capacitive sensing
oscillator signal, Timer1 will use the CPS A signal and
Timer3 will use the CPS B signal (see Table 13-1).
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. Only one
dedicated internal oscillator circuit is available. See
Section 13.4
information.

• Timer1/3 enabled after POR reset
• Write to TMRxH or TMRxL
• Timer1/3 is disabled
• Timer1/3 is disabled (TMRxON = 0)
INTERNAL CLOCK SOURCE
EXTERNAL CLOCK SOURCE
In Counter mode, a falling edge must be
registered by the counter prior to the first
incrementing rising edge after any one or
more of the following conditions:
when TxCKI is high, then Timer1/3 is
enabled (TMRxON=1) when TxCKI is
low.
