Output Compare Function

This function detects matches (compare match) between the content of the TRDGRji (j = either A, B, C, or D)

from the TRDIOji pin. Since this function is enabled with a combination of the TRDIOji pin and TRDGRji

Figure 16.83 shows a Block Diagram of Output Compare Function, Table 16.39 lists the Output Compare

Function Specifications. Figures 16.84 to 16.95 list the Registers Associated with Output Compare Function,

and Figure 16.96 shows an Operating Example of Output Compare Function.
