LO_DET_VDD

1b

Line output. VDDh power detection function

1: ON

0: OFF

LO_GAIN

1b

Line output. Amplifier gain setting

1: 6.5dB 0: 0dB

[1]

LO_VREFSW

1b

Line output. Effective for pin state control and power DOWN ([LO_PDX]=0)

1: LOUT_L and LOUT_R pins become the VREF level output.

0: LOUT_L and LOUT_R pins become Hi-Z.

[0]

LO_MUTE

1b

Line output. MUTE setting

1: ON 0: OFF

VDDh power detection function (operation for setting of [LO_MUTE]=0 and [LO_PDX]=1)

When VDDh power supply becomes 4.0V (TYP) or less, the line output is automatically set to the state equivalent to

"[LO_MUTE]=1, [LO_PDX]=0."

When VDDh power supply returns to 4.3V (TYP) or more, the line output is automatically set to the state equivalent to

"[LO_MUTE]=0, [LO_PDX]=1."

Refer to "1. Reference power supply, line out start/stop sequence."
