9.5.9
When the OCRAMS bit in TOCR is set to 1, the contents of OCRAR and OCRAF are
automatically added to OCRA alternately, and when an OCRA compare-match occurs a write to
OCRA is performed. Figure 9.14 shows the OCRA write timing.
9.5.10
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 9.15 shows the timing of setting the mask
signal. Figure 9.16 shows the timing of clearing the mask signal.
