The INT3 interrupt is generated by an INT3 input. Set the TCC07 bit in the TCC0 register to 0 (INT3).
When the TCC06 bit in the TCC0 register is set to 0, an INT3 interrupt request is generated in synchronization
with the count source of timer C. If the TCC06 bit is set to 1, the INT3 interrupt request is generated when an
INT3 input occurs.
The INT3 input contains a digital filter. The INT3 level is sampled every sampling clock cycle and if the
sampled input level matches three times, the IR bit in the INT3IC register is set to 1 (interrupt requested). The
sampling clock is selected by bits TCC11 to TCC10 in the TCC1 register. If filter is selected, the interrupt
request is generated in synchronization with the sampling clock, even if the TCC06 bit is set to 1. The P3_3 bit
in the P3 register indicates the value before filtering regardless of the contents set in bits TCC11 to TCC10.
The INT3 pin is used with the TCIN pin.
If the TCC07 bit is set to 1 (fRING128), the INT3 interrupt is generated by the fRING128 clock. The IR bit in
the INT3IC register is set to 1 (interrupt requested) every fRING128 clock cycle or every half fRING128 clock
cycle.
Figure 12.15 shows the TCC0 Register and Figure 12.16 shows the TCC1 Register.

Change this bit w hen the TCC00 bit is set to 0 (count stops).
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.
When the TCC13 bit is set to 1 (output compare mode) and an INT3
setting value of the TCC06 bit, an interrupt request is generated.
