(2) Input Capture Timing with Noise Canceler: The noise canceler samples the FTI input, and
does generate an internal input capture signal until three to four sampling clock cycles after the rise
or fall of FTI. Figure 7-9 shows the timing.
If the upper byte of the ICR is being read when the internal input capture signal should be
generated, the internal input capture signal is additionally delayed by one system clock cycle (Ø).
7.4.5 Timing of Input Capture Flag (ICF) Setting
The input capture flag ICF is set to 1 by the internal input capture signal. The FRC contents are
transferred to the ICR at the same time. Figure 7-12 shows the timing of this operation.
