Introduction
The Timer1 module is a 16-bit timer/counter consisting of two 8-bit registers (TMR1H and
TMR1L) which are readable and writable. The TMR1 Register pair (TMR1H:TMR1L) increments
from 0000h to FFFFh and rolls over to 0000h. The Timer1 Interrupt, if enabled, is generated on
overflow which is latched in the TMR1IF interrupt flag bit. This interrupt can be enabled/disabled
by setting/clearing the TMR1IE interrupt enable bit.
Timer1 can operate in one of three modes:
• As a synchronous timer
• As a synchronous counter
• As an asynchronous counter
The operating mode is determined by clock select bit, TMR1CS (T1CON<1>), and the synchro-
nization bit, T1SYNC
In timer mode, Timer1 increments every instruction cycle. In counter mode, it increments on
every rising edge of the external clock input on pin T1CKI.
Timer1 can be turned on and off using theTMR1ON control bit (T1CON<0>).
Timer1 also has an internal “reset input”, which can be generated by a CCP module.
Timer1 has the capability to operate off an external crystal. When the Timer1 oscillator is enabled
(T1OSCEN is set), the T1OSI and T1OSO pins become inputs. That is, their corresponding TRIS
values are ignored.

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