2. Increment timing
TCG is incremented by internal clock input. Bits CKS1 and CKS0 in TMG select one of four
internal clock sources (ø/64, ø/32, ø/2, or øw/4) created by dividing the system clock (ø) or watch
clock (øw).

For input capture input, dedicated input capture functions are provided for rising and falling
edges.
Figure 9.10 shows the timing for rising/falling edge input capture input.
When noise cancellation is performed on the input capture input, the passage of the input
capture signal through the noise canceler results in a delay of five sampling clock cycles from
the input capture input signal edge.
Figure 9.11 shows the timing in this case.
