NEN2: Second-Stage Notch Filter Enable
Default value: 0
The PCM1870 has a two-stage notch filter. The two stages can separately set filter characteristics. This bit is
used to enable the second stage.
NEN2 = 0
NEN2 = 1
Disabled (default)
Enabled
NEN1: First-Stage Notch Filter Enable
Default value: 0
The PCM1870 has a two-stage notch filter. The two stages can separately set filter characteristics. This bit is
used to enable the first stage.
NEN1 = 0
NEN1 = 1

NUP2: Second-Stage Notch Filter Coefficients Update
Default value: 0
This bit is used to update the coefficients for the second-stage notch filter. The coefficients written to registers
101, 102, 103, 104 are updated when NUP2 = 1.
NUP2 = 0
NUP2 = 1
No update (default)

NUP1: First-Stage Notch Filter Coefficients Update
Default value: 0
This bit is used to update the coefficients for the first-stage notch filter. The coefficients written to registers 97,
98, 99, 100 are updated when NUP1 = 1.
NUP1 = 0
NUP1 = 1
No update (default)
