10.17.1
The notch filter for each band is defined by three, 12-bit coefficients: NTCHA1, NTCHA2
and NTCHB. The
bit field that specifies the first coefficient (NTCHA1) for DS1. Bits 3:0 of the NTCHA_H
register (5DBF
The corresponding registers for the second downstream channel (DS2), the first
upstream channel (US1) and the second upstream channel (US2) have the same names
and layout, but unique addresses. See
these registers.
For details on notch filters, refer to standards documents (see
