when “SW1SEL[2:0]=001”), the ‘Sound’ and ‘Silence’ detection is performed on the data before passing through the
ADC output volume. In addition, when the non-PCM data flag is output from NPCMF, the judgment levels set by
YLEVEL[2:0] and NLEVEL[2:0] are ignored, and 0 data detection is executed. When all 24-bit of data of each
channel are “0”, this is judged to be ‘Silence’ status, and “L” is output from DSTATE. Note that digital audio data
‘Sound’ and ‘Silence’ detection is not performed on the MPOUT[4:1] output (SW2SEL[2:0] register setting).
2:0 register is not output from MCKOUT, BCKOUT, and LRCKOUT pins. Therefore, the DSTATE is not changed
from the result before.
