bit[29:16] EDESP [13:0](Error DES pointer)
The EDESP[13:0] bits indicate the DESP of the DES that has caused a transfer error. In the case of EST
≠ 000, even if a new transfer error occurs, the EDESP[13:0] bits keep the DESP of the DES of the
previous transfer error. In the case of EST = 000, the value of the EDESP[13:0] bits is indeterminate. The
EDESP[1:0] bits always read "0".

Writing
Writing a value to these bits does not cause any operation to be executed.
Reading
The EDESP[13:0] bits indicate the DESP of the DES that has caused a transfer error.
bit[31:30] Reserved
The read value is "00". The value written to these bits is ignored.
