14.1
Timer3 can operate in one of three modes:
• Timer
• Synchronous Counter
• Asynchronous Counter
The operating mode is determined by the clock select
bit, TMR3CS (T3CON<1>). When TMR3CS is cleared
(= 0), Timer3 increments on every internal instruction

Note 1: When enable bit, T1OSCEN, is cleared, the inverter and feedback resistor are turned off to eliminate power drain.

or the Timer1 oscillator, if enabled.
As with Timer1, the RC1/T1OSI/UOE and RC0/
T1OSO/T13CKI pins become inputs when the Timer1
oscillator is enabled. This means the values of
TRISC<1:0> are ignored and the pins are read as ‘0’.
