13.1
Timer1 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 Timer1 Clock
Select bit, TMR1CS (T1CON<1>).

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

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/CCP2/FLTA 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 (see
