Input Capture Function: In the input capture mode, the TCNT value is transferred into the TGR

Detection can take place on the rising edge, falling edge, or both edges. Channels 0 and 1 can use

other channel counter input clocks or compare-match signals as input capture sources.

The procedure for selecting the input capture operation (figure 12.13) is:

1.Set the TIOR to select the input capture function of the TGR, then select the input capture

source, and rising edge, falling edge, or both edges as the input edge.

2.Set the CST bit in the TSTR to 1 to start the TCNT counting.
