17.1
The Timer1 module is a 16-bit incrementing counter
which is accessed through the TMR1H:TMR1L register
pair. Writes to TMR1H or TMR1L 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 is enabled by configuring the TMR1ON and
TMR1GE bits in the T1CON and T1GCON registers,
respectively.

When the internal clock source is selected the
TMR1H:TMR1L register pair will increment on multiples
of F
When the F
Timer1 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
value. To utilize the full resolution of Timer1, an
asynchronous input signal must be used to gate the
Timer1 clock input.
The following asynchronous sources may be used:
• Asynchronous event on the T1G pin to Timer1
17.2.2
When the external clock source is selected, the Timer1
module may work as a timer or a counter.
When enabled to count, Timer1 is incremented on the
rising edge of the external clock input T1CKI. The
external clock source can be synchronized to the
microcontroller
asynchronously.
