12.3.6
TMRX has input capture registers of TICR, TICRR, and TICRF. Narrow pulse width can be
measured with TICRR and TICRF, using one capture operation controlled by the ICST bit in the
TCONRI register of the timer connection. When TMRIX detects a rising and falling edge
successively after the ICST bit has been set to 1, the values of TCNT at that time are transferred to
TICRR and TICRF and ICST bit is cleared to 0.
The TMRIX input signal can be selected by setting other bits in the TCONRI register.
(1) Input capture input timing
Figure 12.9 shows the timing of the input capture operation.
If the input capture signal enters while TICRR and TICRF are being read, it is internally delayed
one system clock ( ) period. Figure 12.10 shows the timing of this operation.
