TCC02

TCC00

When using the INT3

_____

filter, the INT3

_____

interrupt is generated synchronizing w ith the clock for the digital filter.

Change this bit w hen the TCC00 bit is set to “0” (count stop).

The IR bit in the INT3IC register may be set to “1” (requests interrupt) w hen the TCC03, TCC04, TCC06 and TCC07

bits are rew ritten. Refer to 20.2.5 Changing Interrupt Factor.

TCC07

When the TCC13 bit is set to “1” (output compare mode) and INT3

_____

interrupt is input, regardless of the

setting value of the TCC06 bit, an interrupt request is generated.
