Window Mode

In the window mode, the up-counter counts up at the rising edge of the pulse that is logical ANDed product

of the input pulse to the TC1 pin (window pulse) and the internal source clock. Either the positive logic (count

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

When a match between the up-counter and the TC1DRA value is detected, an INTTC1 interrupt is generated

and the up-counter is cleared.

Define the window pulse to the frequency which is sufficiently lower than the internal source clock pro-

grammed with TC1CR<TC1CK>.
