DACH: Switch Control from DAC to Headphone-Amp
0: OFF (Default)
1: ON
MINH: Switch Control from MIN pin to Headphone-Amp
0: OFF (Default)
1: ON
HPM: Headphone-Amp Mono Output Select
0: Stereo (Default)
1: Mono
When the HPM bit = “1”, DAC output signal is output to Lch and Rch of the Headphone-Amp as (L+R)/2.
IVOLC: Input Digital Volume Control Mode Select
0: Independent
1: Dependent (Default)
When IVOLC bit = “1”, IVL7-0 bits control both Lch and Rch volume level, while register values of IVL7-0
bits are not written to IVR7-0 bits. When IVOLC bit = “0”, IVL7-0 bits control Lch level and IVR7-0 bits
control Rch level, respectively.
