The DADR register is the digital audio data input to the analog DAC.
The digital audio data format must be in 32 bit words. The upper 16 bits will be used as the
input to the 24 bit left channel of the analog DAC, left justified. The lower 16 bits will be
used as the input to the 24 bit right channel of the analog DAC, left justified. All data must
be in binary twos complement format.
Notes:
−
The DADR register accepts 32 bit word writes only.
Please set the same value as DADR[31:16] and DADR[15:0] when outputting it by monaural.
