• Timer
• Synchronous Counter
• Asynchronous Counter

The operating mode is determined by the clock select
bit, TMR3CS of the T3CON register. When TMR3CS is
cleared (= 0), Timer3 increments on every internal
instruction cycle (F
increments on every rising edge of the Timer1 external
clock input or the Timer1 oscillator, if enabled.
As with Timer1, the digital circuitry associated with the
RC1/T1OSI and RC0/T1OSO/T13CKI pins is disabled
when the Timer1 oscillator is enabled. This means the
values of TRISC<1:0> are ignored and the pins are
read as ‘0’.
