This function is to detect the match (compare match) of the content in the TRDGRji (j = either A, B, C and D)
register with the content in the TRDi (i = 0 or 1) register. When the content matches, any level is output from
the TRDIOji pin. Since this function is enabled with a combination of the TRDIOji pin and TRDGRji register,
any of the output compare function, other modes or functions can be selected every pin.
Figure 14.47 shows the Block Diagram of Output Compare Function, Table 14.25 lists the Output Compare
Function Specifications. Figures 14.48 to 14.59 list the Registers Associated with Output Compare Function
and Figure 14.60 shows the Operating Example of Output Compare Function.
