Nothing is assigned to the b5 in the TRDSR0 register. When w riting to the b5, w rite 0. When reading, its 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 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.
