Datasheet

Mono Status (SMONO)

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.

Headphone Amplifier Status (SHP)

0 = The headphone amplifiers are operating.

1 = The headphone amplifiers are not operating.

SHP indicates whether the headphone amplifiers are

operating or not operating.

Line Output Status (SLO)

0 = The line outputs are enabled.

1 = The line outputs are disabled.

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.

Line Input Status (SLI)

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.

DAC Status (SDAC)

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.
