In output compare mode, the internal count source divided by 2 is counted using the 4-bit or 8-bit counter and
compare value match is detected with the 8-bit counter. Figure 14.71 shows a Block Diagram of Output
Compare Mode and Table 14.27 lists the Specifications of Output Compare Mode. Figures 14.72 to 14.76 show
the registers associated with output compare mode, and Figure 14.77 shows the Operating Example in Output
Compare Mode.
