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
