Select Function
1. The digital filter delay and one count source (max.) delay are generated for the INT3 interrupt.
2. Read the TC and TM0 registers in 16-bit unit.
Input capture mode is mode to input an edge to the TCIN pin or the fRING128 clock as trigger to latch
the timer value and generates an interrupt request. The TCIN input contains a digital filter and this
prevents an error caused by noise or so on from occurring. Table 13.11 shows Specification of Input
Capture Mode. Figure 13.30 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 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 measurement pulse is input [INT3 interrupt]
• When Timer C overflows [Timer C interrupt]
Programmable I/O port or measurement pulse input (INT3 interrupt input)
Programmable I/O port
When the TCC00 bit in the TCC0 register is set to “0” (capture disabled)
• The count value can be read out by reading the TC register.
• The count value at measurement pulse active edge input can be read out
Write to the TC and TM0 registers is disabled
• INT3/TCIN polarity select function
• Digital filter function
• Trigger select function
of measurement pulse
by reading the TM0 register.
The TCC03 to TCC04 bits can select the active edge of measurement
pulse
The TCC11 to TCC10 bits can select the digital filter sampling frequency
The TCC07 bit can select the TCIN input or the fRING128
