Description
Reserved
Enable DACs High Pass Filter: When set to
‘1’b, will enable a high pass filter to remove any
DC component.
‘0’b - Disable HPF.
‘1’b - Enable HPF.
Power Down Internal References (PDREF):
When set to ‘1’b, will ramp the internal voltage
references down. This should be used prior to
removing operating voltages from the codec.
‘0’b - Normal Operation.
‘1’b - Power down internal references.
Disable Coefficient Index Auto-Increment:
Specifies if the Coefficient Index value will be
automatically incremented following a read or
write operation. Auto increment is supported by
Vista OS.
‘0’b - auto increment coefficient index following a
read or write.
‘1’b - do not auto increment coefficient index fol-
lowing a read or write.
Reserved
Mute DAC Outputs on FIFO Error: Specifies to
force a Mute condition if an under-run or over-run
condition occurs on the HD Audio FIFO memory.
The transition to Mute will occur as per the set-
tings of each of the DACx SZCMode bits.
‘0’b - Disable Mute DAC Outputs on FIFO Error.
‘1’b - Enable Mute DAC Outputs on FIFO Error.
DAC3 SZCMode[1:0]: Same function as DAC1.
See below.
DAC2 SZCMode[1:0]: Same function as DAC1.
See below.
