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 14.18 lists the Specifications of Output Compare Function, Figure 14.46 shows a Block Diagram of
Output Compare Function, Figures 14.47 to 14.49 show the registers associated with the output compare
function, Table 14.19 lists the Functions of TRCGRj Register when Using Output Compare Function, and
Figure 14.50 shows an Operating Example of Output Compare Function.
