The Timer1 module is a 16-bit timer/counter with the
following features:
• 16-bit timer/counter register pair (TMR1H:TMR1L)
• Programmable internal or external clock source
• 3-bit prescaler
• Optional LP oscillator
• Synchronous or asynchronous operation
• Timer1 gate (count enable) via comparator or
• Interrupt on overflow
• Wake-up on overflow (external clock,
• Clock source for LCD module
Figure 6-1 is a block diagram of the Timer1 module.

ST Buffer is low power type when using LP oscillator, or high speed type when using T1CKI.
Timer1 register increments on rising edge.
Synchronize does not operate while in Sleep.
SYNCC2OUT is synchronized when the C2SYNC bit of the CMCON1 register is set.

6.1
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. When used with an external clock source, the
module can be used as either a timer or counter.
6.2
The TMR1CS bit of the T1CON register is used to select
the clock source. When TMR1CS = 0, the clock source
is F
