Section 11 16-Bit Free-Running Timer (FRT)
11.5.9
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 11.14 shows the OCRA write timing.
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.
