1. The INT3 interrupt includes a digital filter delay and one count source (max.) delay.
2. Read registers TC and TM0 in 16-bit unit.
In input capture mode, the edge of the TCIN pin input signal or the fRING128 clock is used as a trigger to latch
the timer value and generate an interrupt request. The TCIN input contains a digital filter, and this prevents
errors caused by noise or the like from occurring. Table 14.11 shows the Input Capture Mode Specifications.
Figure 14.30 shows an Operating Example in Input Capture Mode.

• Increment
• Transfer the value in the TC register to the TM0 register at the active edge
• The value in the TC register is set to 0000h when the count stops.
The TCC00 bit in the TCC0 register is set to 1 (count starts).
The TCC00 bit in the TCC0 register is set to 0 (count stops).
• When the active edge of the measured pulse is input [INT3 interrupt].
• When timer C overflows [timer C interrupt].

Bits TCC03 to TCC04 can select the active edge of the measured pulse.
Bits TCC11 to TCC10 can select the digital filter sampling frequency.
The TCC07 bit can select the TCIN input or the fRING128.
