The TRDGRCi register can be used as output control of the TRDIOAi pin and the TRDGRDi register can be
used as output control of the TRDIOBi pin. Therefore, each pin output can be controlled as follows:
Change output pins in the TRDGRCi and TRDGRDi registers as below:
• TRDIOAi output is controlled by the values in the TRDGRAi and TRDGRCi registers.
• TRDIOBi output is controlled by the values in the TRDGRBi and TRDGRDi registers.
• 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 the different value in the TRDGRCi register and the TRDGRAi register. Also, set the different value in
the TRDGRDi register and the TRDGRBi register.
