NOTES:
1. Change this bit w hen the TCC00 bit is set to 0 (count stops).
2. The IR bit in the INT3IC register may be set to 1 (requests interrupt) w hen the TCC03, TCC04, TCC06, or TCC07 bit is
rew ritten. Refer to 12.5.5 Changing Interrupt Sources .
3. When the TCC13 bit is set to 1 (output compare mode) and INT3
value of the TCC06 bit, an interrupt request is generated.
4. When using the INT3
