Timer3 Operation
Timer3 can operate in one of these modes:
As a timer
As a synchronous counter
As an asynchronous counter
The operating mode is determined by the clock select
bit, TMR3CS (T3CON<1>).
When TMR3CS = 0, Timer3 increments every instruc-
tion cycle. When TMR3CS = 1, Timer3 increments on
every rising edge of the Timer1 external clock input or
the Timer1 oscillator, if enabled.
When the Timer1 oscillator is enabled (T1OSCEN is
set), the RC1/T1OSI and RC0/T1OSO/T13CKI pins
become inputs. That is, the TRISC<1:0> value is
ignored and the pins are read as ‘0’.
Timer3 also has an internal “Reset input”. This Reset
can be generated by the CCP module (see Section 14.0
