Bit
Name Reset R/W Description
No.
7:0
DC_I[7:0]
0x00 R*/W When running dc estimation, this register reflects the 8 LSBs of the dc
estimate in the I channel. When manual dc override is selected, the

Bit
Name Reset R/W Description
No.
7:0
DC_I[15:8]
0x00 R*/W When running dc estimation, this register reflects the 8 MSBs of the dc
estimate in the I channel. When manual dc override is selected, the
override value is written to this register.
