LX2G4:0 = 0 produces a +12 dB gain. LX2G4:0 = “01000” (8 decimal) produces 0 dB gain. Maximum attenuation is
–34.5 dB. Gains referred to 2.0 V p-p full-scale output level.
Reserved for future expansion. Write zeros (LO) to all reserved bits.
Left Auxiliary #2 Mute. This bit, when set HI, will mute the left channel of the Auxiliary #2 input source. This bit is HI
after reset.
RX2G4:0 = 0 produces a +12 dB gain. RX2G4:0 = “01000” (8 decimal) produces 0 dB gain. Maximum attenuation is
–34.5 dB. Gains referred to 2.0 V p-p full-scale output level.
Reserved for future expansion. Write zeros (LO) to all reserved bits.
Right Auxiliary #2 Mute. This bit, when set HI, will mute the right channel of the Auxiliary #2 input source. This bit is
HI after reset.
duces a 0 dB attenuation. Maximum attenuation is –94.5 dB.
Reserved for future expansion. Write zeros (LO) to all reserved bits.
Left DAC Mute. This bit, when set HI, will mute the left channel output. Auxiliary inputs are muted independently with
the Left Auxiliary Input Control Registers. This bit is HI after reset.
produces a 0 dB attenuation. Maximum attenuation must be at least –94.5 dB.
Reserved for future expansion. Write zeros (LO) to all reserved bits.
Right DAC Mute. This bit, when set HI, will mute the right DAC output. Auxiliary inputs are muted independently with
the Right Auxiliary Input Control Registers. This bit is HI after reset.
