Description
Input Capture Start Bit
The TMR_X external reset input (TMRIX) is
connected to the IHI signal. TMR_X has input capture
registers (TICR, 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
