11.7.3
The TMRX has input capture registers (TICR, TICRR, and TICRF). A narrow pulse width can be
measured with TICRR and TICRF, using a single capture. If the falling edge of TMRIX (TMRX
input capture input signal) is detected after its rising edge has been detected, the value of TCNTX
at that time is transferred to both TICRR and TICRF.
Input Timing of Input Capture Signal:
Figure 11.11 shows the timing of the input capture operation.
If the input capture signal is input while TICRR and TICRF are being read, the input capture
signal is delayed by one system clock (φ) cycle. Figure 11.12 shows the timing of this operation.
