The operating mode is determined by the clock select
bit, TMR3CS (T3CON<1>). When TMR3CS is cleared
(= 0), Timer3 increments on every internal instruction
cycle (F
on every rising edge of the Timer1 external clock input
or the Timer1 oscillator, if enabled.
As
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’.
