The output compare mode is to count the internal count source divided-by-2 using the 4-bit or 8-bit counter and
detect the compare value match with the 8-bit counter.
Figure 14.114 shows the Block Diagram of Output Compare Mode and Table 14.37 lists the Output Compare
Mode Specifications. Figures 14.115 to 14.119 show the Registers Associated with Output Compare Mode and
Figure 14.120 shows the Operation in Output Compare Mode.
