DESCRIPTION

R96 (60h)

Analogue

HP 0

HPOUT1_AUT

O_PU

Enables automatic power-up of HPOUT1 by monitoring

HPOUT1L_ENA and HPOUT1R_ENA

0 = Disabled

1 = Enabled

HPOUT1L_RM

V_SHORT

Removes HPOUT1L short

0 = HPOUT1L short enabled

1 = HPOUT1L short removed

For normal operation, this bit should be set as the final

step of the HPOUT1L Enable sequence.

HPOUT1L_OU

Enables HPOUT1L output stage

0 = Disabled

1 = Enabled

For normal operation, this bit should be set to 1 after

the DC offset cancellation has been scheduled.

HPOUT1L_DL

Enables HPOUT1L intermediate stage

0 = Disabled

1 = Enabled

For normal operation, this bit should be set to 1 after

the output signal path has been configured, and before

DC offset cancellation is scheduled. This bit should be

set with at least 20us delay after HPOUT1L_ENA.

HPOUT1R_RM

V_SHORT

Removes HPOUT1R short

0 = HPOUT1R short enabled

1 = HPOUT1R short removed

For normal operation, this bit should be set as the final

step of the HPOUT1R Enable sequence.

HPOUT1R_OU

Enables HPOUT1R output stage

0 = Disabled

1 = Enabled

For normal operation, this bit should be set to 1 after

the DC offset cancellation has been scheduled.

HPOUT1R_DL

Enables HPOUT1R intermediate stage

0 = Disabled

1 = Enabled

For normal operation, this bit should be set to 1 after

the output signal path has been configured, and before

DC offset cancellation is scheduled. This bit should be

set with at least 20us delay after HPOUT1R_ENA.
