When MINH bit is “1”, monaural signal is input to HP-Amp.
When the HPM bit = “1”, DAC output signal is output to Lch and Rch of the Headphone-Amp as (L+R)/2.
HPM bit must be changed when DAC is powered-down.
When AVOLC bit = “1”, AVL7-0 bits control both Lch and Rch volume level, while register values of
AVL7-0 bits are not written to AVR7-0 bits. When AVOLC bit = “0”, AVL7-0 bits control Lch level and
AVR7-0 bits control Rch level, respectively.
HPG bit must be changed when the Headphone-Amp is powered-down.
When FIL3 bit is “1”, the settings of F3A13-0 and F3B13-0 bits are valid. When FIL3 bit is “0”, FIL3 block is
through (0dB).
When EQ bit is “1”, the settings of EQA15-0, EQB13-0 and EQC15-0 bits are valid. When EQ bit is “0”, EQ
block is through (0dB).
When HPF bit is “1”, the settings of F1A13-0 and F1B13-0 bits are valid. When HPF bit is “0”, HPF block is
through (0dB).
