This function detects when the contents of the TRC register (counter) and the TRCGRj register (j = A, B, C, or D)
match (compare match). When a match occurs a signal is output from the TRCIOj pin at a given level. The output
compare function, or other mode or function, can be selected for each individual pin.
Table 19.9 lists the Specifications of Output Compare Function, Figure 19.9 shows a Block Diagram of Output
Compare Function, Table 19.10 lists the Functions of TRCGRj Register when Using Output Compare Function,
and Figure 19.10 shows an Operating Example of Output Compare Function.
