11.3.9
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 function is generated.
The mask signal is set by the input capture signal. The mask signal setting timing is shown in
figure 11.15.
The mask signal is cleared by the sum of the ICRD contents and twice the OCRDM contents, and
an FRC compare-match. The mask signal clearing timing is shown in figure 11.16.
