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.
Change output pins in registers TRDGRCi and TRDGRDi as follows:
• Select 0 (change TRDGRji register output pin) by the IOj3 (j = C or D) bit in the TRDIORCi register.
• Set the BFji bit in the TRDMR register to 0 (general register).
• Set different values in registers TRDGRCi and TRDGRAi. Also, set different values in registers TRDGRDi
Figure 20.13 shows an Operating Example When TRDGRCi Register is Used for Output Control of TRDIOAi
Pin and TRDGRDi Register is Used for Output Control of TRDIOBi Pin.
