Selectable functions
This function measures the width or period of an external signal. An external signal input to the TRCIOj (j = A, B,
C, or D) pin acts as a trigger for transferring the content of the TRC register (counter) to the TRCGRj register
(input capture). The input capture function, or any other mode or function, can be selected for each individual pin.
Table 19.7 lists the Input Capture Function Specifications, Figure 19.7 shows a Block Diagram of Input Capture
Function, Table 19.8 lists the Functions of TRCGRj Register when Using Input Capture Function, and Figure 19.8
shows an Operating Example of Input Capture Function.

Increment
• The CCLR bit in the TRCCR1 register is set to 0 (free-running operation):
1 (count starts) is written to the TSTART bit in the TRCMR register.
Programmable I/O port or INT0 interrupt input
The count value can be read by reading TRC register.
f1, f2, f4, f8, f32, or
external signal (rising edge) input to the TRCCLK pin
• The CCLR bit in the TRCCR1 register is set to 1 (TRC register is set to
0 (count stops) is written to the TSTART bit in the TRCMR register.
The TRC register retains a value before the count stops.
• Input capture (active edge of the TRCIOj input)
• TRC register overflows
Programmable I/O port or input capture input
(selectable for each individual pin)
The TRC register can be written to.
• Input-capture input pin selection
• Input-capture input active edge selection
• Buffer operation (Refer to 19.3.2 Buffer Operation .)
• Digital filter (Refer to 19.3.3 Digital Filter .)
• Timing for setting the TRC register to 0000h
1/fk × 65,536
fk: Frequency of count source
0000h by TRCGRA compare match):
1/fk × (n + 1)
n: Value set in TRCGRA register
One or more of pins TRCIOA, TRCIOB, TRCIOC, and TRCIOD
Rising edge, falling edge, or both rising and falling edges
Overflow or input capture
