10.2.4 INT3 Interrupt
INT3 interrupts are triggered by INT3 inputs. The TCC07 bit in the TCC0 register should be se to “0”
(INT3). The INT3 input has a digital filter which can be sampled by one of three sampling clocks. The
sampling clock is selected using the TCC11 to TCC10 bits in the TCC1 register. The IR bit in the
INT3IC register is set to “1” (interrupt requested) when the sampled input level matches three times.
The P3_3 bit in the P3 register indicates the previous value before filtering regardless of values set in
the TCC11 to TCC10 bits.
The INT3 pin is shared with the TC
