Descriptions
1 = The headphone amplifier outputs are in mono
mode.
0 = The headphone amplifier outputs are in stereo
mode.
SMONO indicates whether the headphone outputs are
in mono or stereo mode. In mono mode, the left and
right audio signals are mixed and output to the left
headphone output. Set MONO = 1 in the general-pur-
pose register (register 0x3, bit B2) to enter mono mode.
0 = The headphone amplifiers are operating.
1 = The headphone amplifiers are not operating.
SHP indicates whether the headphone amplifiers are
operating or not operating.

SLO indicates whether the line outputs are enabled or
disabled. Set LNOEN = 1 in the enable register (regis-
ter 0x5, bit B2) to enable the line outputs.
0 = The line inputs are enabled.
1 = The line inputs are disabled.
SLI indicates whether the line inputs are enabled or dis-
abled. Set LNIEN = 1 in the enable register (register
0x5, bit B1) to enable the line inputs.
0 = The DAC is operating and has completed a soft-
start sequence.
1 = The DAC is not operating and has completed a
soft-stop sequence.
SDAC indicates whether the DAC is operational and
receiving valid clock signals, or not operating.
