Input Capture Start Bit
TMR_X has input capture registers (TICRR and
TICRF). TICRR and TICRF can measure the width
of a pulse by means of a single capture operation
under the control of the ICST bit. When a rising edge
followed by a falling edge is detected on TMRIX after
the ICST bit is set to 1, the contents of TCNT at
those points are captured into TICRR and TICRF,
respectively, and the ICST bit is cleared to 0.
[Clearing condition]
When a rising edge followed by a falling edge is
detected on TMRIX
[Setting condition]
When 1 is written in ICST after reading ICST = 0
