The INT3 interrupt is generated by the 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”, the INT3 interrupt request is generated
synchronizing with the count source of timer C. When the TCC06 bit is set to “1”, the INT3 interrupt
request is generated when the INT3 is input.
The INT3 input contains a digital filter. The IR bit in the INT3IC register is set to “1” (interrupt
requested) when the INT3 level is sampled for every sampling clock and the sampled input level
matches three times. The sampling clock is selected by the TCC11 to TCC10 bits in the TCC1
register. When selecting “Filter”, the interrupt request is generated synchronizing with the sampling
clock even if the TCC06 bit is set to “1”. The P3_3 bit in the P3 register indicates the previous value
before filtering regardless of the contents set in the TCC11 to TCC10 bits.
The INT3 pin is used with the TCIN pin.
When setting the TCC07 bit 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 11.15 shows the TCC0 Register and Figure 11.16 shows the TCC1 Register.
0
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 Inte rrupt Factor.
When the TCC13 bit is set to “1” (output compare mode) and INT3
setting value of the TCC06 bit, an interrupt request is generated.
