(2) Changing Output Pins in Registers TRDGRCi (i = 0 or 1) and TRDGRDi
The TRDGRCi register can be used for output control of the TRDIOAi pin, and the TRDGRDi register can be used
for output control of the TRDIOBi pin. Therefore, each pin output can be controlled as follows:
 TRDIOAi output is controlled by the values in registers TRDGRAi and TRDGRCi.
 TRDIOBi output is controlled by the values in registers TRDGRBi and TRDGRDi.
Figure 8-50. Changing Output Pins in Registers TRDGRCi and TRDGRDi
Change output pins in registers TRDGRCi and TRDGRDi as follows:
• Select 0 (TRDGRji register output pin is changed) using the IOj3 (j = C or D) bit in the TRDIORCi register.
• Set the TRDBFji bit in the TRDMR register to 0 (general register).
• Set different values in registers TRDGRCi and TRDGRAi. Also, set different values in registers TRDGRDi and
TRDGRBi.
