TIF1 [1]: Timer Interrupt Flag 1
It indicates the interrupt status of the timer 1.
0 = It indicates that the timer 1 does not count down to zero yet. Software can reset this bit after the
1 = It indicates that the counter of timer 1 is decremented to zero; the timer interrupt 1 is generated if it
TIF1 [0]: Timer Interrupt Flag 0
It indicates the interrupt status of the timer 0.
0 = It indicates that the timer 0 does not count down to zero yet. Software can reset this bit after the
1 = It indicates that the counter of timer 0 is decremented to zero; the timer interrupt 0 is generated if it
