Timing of Setting IMFA, IMFB for Input Capture: IMFA and IMFB are set to 1 by an input
capture signal. At this time, the TCNT contents are transferred to GR. Figure 10.55 shows the
timing.
Timing of Setting Overflow Flag (OVF): OVF is set to 1 when TCNT overflows from H'FFFF
to H'0000 or underflows from H'0000 to H'FFFF. Figure 10.56 shows the timing.
