Nothing is assigned to b5 in the TRDSR0 register. When w riting to b5, w rite 0. When reading, the content is 1.
The w riting results are as follow s:
• This bit is set to 0 w hen the read result is 1 and 0 is w ritten to the same bit.
• This bit remains unchanged even if the read result is 0 and 0 is w ritten to the same bit (this bit remains
• This bit remains unchanged if 1 is w ritten to it.
Including w hen the BFji bit in the TRDMR register is set to 1 (TRDGRji is used as the buffer register).
