Window Mode
In the window mode, the up-counter counts up at the rising edge of the pulse that is logical ANDed prod-
When a match between the up-counter and the TC1DRA value is detected, an INTTC1 interrupt is gener-
Define the window pulse to the frequency which is sufficiently lower than the internal source clock program-
