up during high-going pulse) or negative logic (count up during low-going pulse) can be selected.

grammed with TC1CR<TC1CK>.
In the window mode, the up-counter counts up at the rising edge of the pulse that is logical ANDed product
When a match between the up-counter and the TC1DRA value is detected, an INTTC1 interrupt is generated
Define the window pulse to the frequency which is sufficiently lower than the internal source clock pro-
