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,
• Time base for the Capture/Compare function
• Special Event Trigger (with ECCP)
• Comparator output synchronization to Timer1
Figure 7-1 is a block diagram of the Timer1 module.
7.1
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.
