General Purpose Register (Index 20h)
3D
3D Enable. When ‘set’, the 3D bit enables the CrystalClearTM 3D stereo enhancement. This
function is not available in DAC Direct Mode (DDM).
MIX
Mono Output Select. The MIX bit selects the source for the Mono Out output. When ‘set’, the
microphone input is selected. When ‘clear’, the stereo-to-mono mixer is selected.
MS
Microphone Select. The MS bit determines which of the two Mic inputs are passed to the mixer.
When ‘set’, the MIC2 input is selected. When ‘clear’, the MIC1 input is selected.
LPBK
Loopback Enable. When ‘set’, the LPBK bit enables the ADC/DAC Loopback Mode. This bit
routes the output of the ADCs to the input of the DACs without involving the AC-link.
Default
0000h
4.12
3D Control Register (Index 22h)
S[3:0]
Spacial Enhancement Depth. These bits control the amount of “space” added to the output ste-
reo signal. When S[3:0] = 0000, the minimum amount of spatial enhancement is added. When
S[3:0] = 1111, the maximum amount of spatial enhancement is added. The 3D function is en-
abled and disabled by the 3D bit in the General Purpose Register (Index 20h).
Default
0000h. This value corresponds to minimum spatial enhancement added to the output signal.
