8.3.3 Output Compare Function
This function detects matches (compare match) between the content of the TRDGRji register (j = A, B, C, or D) and the
content of the TRDi register (counter) (i = 0 or 1). When the contents match, an arbitrary level is output from the TRDIOji
pin. Since this function is enabled with a combination of the TRDIOji pin and TRDGRji register, the output compare function,
or any other mode or function, can be selected for each individual pin.
Figure 8-48 shows the Block Diagram of Output Compare Function, Table 8-13 lists the Output Compare Function
Specifications, and Figure 8-49 shows an Operation Example of Output Compare Function.
