DESCRIPTION

REFER TO

R42 (2Ah)

Output ctrl

THERR_ACT

Thermal Shutdown enable

0 = Disabled

1 = Enabled

When THERR_ACT = 1, then an overtemperature

condition will cause the speaker outputs to be disabled.

P_ENA

Buffered VMID to SPKOUTL Enable

0 = Disabled

1 = Enabled

LINER_VMID_

OP_ENA

Buffered VMID to LINEOUTR Enable

0 = Disabled

1 = Enabled

LINEL_VMID_

OP_ENA

Buffered VMID to LINEOUTL Enable

0 = Disabled

1 = Enabled

LINER_MUTE

0 = Disable Mute

1 = Enable Mute

LINEL_MUTE

LINEOUTL Output Mute

0 = Disable Mute

1 = Enable Mute

SPKR_DISCH

Discharges SPKOUTR output via approx 4k resistor

0 = Not active

1 = Actively discharging SPKOUTR

SPKL_DISCH

Discharges SPKOUTL output via approx 4k resistor

0 = Not active

1 = Actively discharging SPKOUTL

LINER_DISCH

Discharges LINEOUTR output via approx 4k resistor

0 = Not active

1 = Actively discharging LINEOUTR

LINEL_DISCH
