The notch filter for each band is defined by three, 12-bit coefficients: NTCHA1, NTCHA2
and NTCHB. The
coefficient, NTCHB for DS1, and the notch filter enable bit.
the eight most significant bits of NTCHB. Bits 6:4 are reserved.
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.
