11.5.10 Mask Signal Generation Timing
When the ICRDMS bit in TOCR is set to 1 and the contents of OCRDM are other than H'0000, a
signal that masks the ICRD input capture signal is generated. The mask signal is set by the input
capture signal. The mask signal is cleared by the sum of the ICRD contents and twice the
OCRDM contents, and an FRC compare-match. Figure 11.15 shows the timing of setting the mask
signal. Figure 11.16 shows the timing of clearing the mask signal.
