Function and Mode
The TRDGRCi register can be used as the buffer register of the TRDGRAi register, and the TRDGRDi register
can be used as the buffer register of the TRDGRBi register by the BFCi and BFDi bits in the TRDMR register.
Buffer operation depends on modes. Table 14.22 lists the Buffer Operation in Each Mode.
Figure 14.29 shows the Buffer Operation in Input Capture Function, and Figure 14.30 shows the Buffer
Operation in Output Compare Function.
• TRDGRAi buffer register: TRDGRCi register
• TRDGRBi buffer register: TRDGRDi register
i = 0 or 1
The above applies to the following conditions:
• The BFCi bit in the TRDMR register is set to 1. (The TRDGRCi register is used as the buffer register of
• The IOA2 to IOA0 bits in the TRDIORAi register are set to 100b (input capture at the falling edge).
