Figure 21.4
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 21.4 shows a Block Diagram of Output Compare
Mode and Table 21.4 lists the Output Compare Mode Specifications. Figure 21.5 shows the Operating Example in
Output Compare Mode.
