When TMR1CS = 0, Timer1 increments every instruc- tion cycle. When TMR1CS = 1, Timer1 increments on every rising edge of the external clock input or the Timer1 oscillator, if enabled. When the Timer1 oscillator is enabled (T1OSCEN is set), the RC1/T1OSI and RC0/T1OSO/T1CKI pins become inputs. That is, the TRISC<1:0> value is ignored, and the pins are read as ‘0’. Timer1 also has an internal “RESET input”. This RESET can be generated by the CCP module (Section 14.0).
