Left DAC1 Digital Mute
0 = Left DAC1 Enabled
1 = Left DAC1 Muted
Left DAC1 Digital Attenuation Select. Least significant bit represents –1.5 dB.
000000 = +0.0 dB Attenuation
111111 = –94.5 dB Attenuation
Right DAC1 Digital Mute
0 = Right DAC1 Enabled
1 = Right DAC1 Muted
Right DAC1 Digital Attenuation Select. Least significant bit represents –1.5 dB.
000000 = +0.0 dB Attenuation
111111 = –94.5 dB Attenuation
Reserved for future expansion. To ensure future compatibility, write “0” to all reserved bits.
Initial default state after reset: 0000 0000 0000 0000 (0000 hex). Cleared to default and cannot be written to when:
the RESET pin is asserted LO; when the PWRDWN pin is asserted LO; or when the PDNO bit in Control Register
Address 0 is set to “1” (all conversions disabled).
