(3) Window mode

In this mode, counting up performed on the rising edge of an internal clock during TC2

external pin input (window pulse) is “H” level. The contents of TC2DR are compared with

the contents of up-counter. If a match found, an INTTC2 interrupt is generated, and the

up-counter is cleared.

The maximum applied frequency (TC2 input) must be considerably slower than the

selected internal clock.

Example: Generates an interrupt, inputting “H” level pulse width of 120 ms or more.
