Section 11 16-Bit Free-Running Timer
11.3.7
The FRC overflow flag (OVF) is set to 1 when FRC overflows (changes from H'FFFF to H'0000).
Figure 11.13 shows the timing of this operation.
11.3.8
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. The OCRA write timing is shown in figure 11.14.
