Initialization
Since Timer1 has a software programmable clock source, there are three examples to show the
initialization of each mode.
Example 12-5
initialization of the external oscillator mode.
Example 12-4:
Example 12-5:
;
; The Timer1 interrupt is disabled, do polling on the overflow bit
;
T1_OVFL_WAIT
;
; Timer has overflowed
;
;
