There are two ways to enable the TMR1 overflow interrupt:
Library Call
To enable the TMR1 Overflow Interrupt through a library call, you must include the
timers16.h
also allows you to select the source (external/internal) of the clock, as well as whether
to treat Timer1 and Timer2 as individual 8-bit timers or as one 16-bit timer.
The following table outlines the
selecting an external or internal clock source:
The following table outlines the
specifying whether to treat Timer1 and Timer2 as individual 8-bit timers or as one
16-bit timer:
#include <timers16.h>
// Enable the TMR1 Overflow interrupt.
// Use Timer1 as an individual 8-bit timer.
#ifdef _EXTERNAL_CLOCK
#else
#endif
Modifying Register Bits
To select the source (external/internal) of the clock, you must clear (internal clock) or
set (external clock input on the TCLK12 pin) the Timer1 Clock Source Select
(TMR1CS) bit – [TCON1<0>].
#ifdef _EXTERNAL_CLOCK
#else
#endif
To specify whether to treat Timer1 and Timer2 as individual 8-bit timers or as one
16-bit timer, you must clear or set, respectively, the Timer2:Timer1 Mode Select (T16)
bit – [TCON1<3>].
#ifdef _16BIT_CLOCK
#else
#endif
