The Timer1 module is a 16-bit timer which can serve as
the time counter for the Real-Time Clock (RTC), or
operate as a free-running, interval timer/counter. Timer1
can operate in three modes:
• 16-Bit Timer
• 16-Bit Synchronous Counter
• 16-Bit Asynchronous Counter
Timer1 also supports these features:
• Timer Gate Operation
• Selectable Prescaler Settings
• Timer Operation during CPU Idle and Sleep
• Interrupt on 16-Bit Period Register Match or

Set the TON bit (= 1).
Select the timer prescaler ratio using the
TCKPS<1:0> bits.
Set the Clock and Gating modes using the TCS
and TGATE bits.
Set or clear the TSYNC bit to configure
synchronous or asynchronous operation.
Load the timer period value into the PR1
register.
If interrupts are required, set the interrupt enable
bit, T1IE. Use the priority bits, T1IP<2:0>, to set
the interrupt priority.
