The Timer1 module is a 16-bit timer, which can serve
as the time counter for the real-time clock, 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

Set the TON bit (= 1) in the T1CON register.
Select the timer prescaler ratio using the
TCKPS<1:0> bits in the T1CON register.
Set the Clock and Gating modes using the TCS
and TGATE bits in the T1CON register.
Set or clear the TSYNC bit in T1CON to select
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.
