When the HPM bit = “1”, (L+R)/2 signals are output to Lch and Rch of the Headphone-Amp. Both PMHPL
and PMHPR bits should be “1” when HPM bit is “1”.
IVOLC: Input Digital Volume Control Mode Select

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.
