The w riting results are as follow s:
• This bit is set to 0 w hen the read result is 1 and w riting 0 to the same bit.
• This bit remains unchanged even if the read result is 0 and w riting 0 to the same bit. (This bit remains 1 even if this
• This bit remains unchanged w hen w riting 1.
Including w hen the BFji bit (j = C or D) in the TRDMR register is set to 1 (TRDGRji is used as the buffer register).
bit is set to 1 from 0 after reading, and w riting 0.)
