§4-10. Description of DAC Block Functions
Zero data detection
When the condition where the lower 4 bits of the input data are DC and the remaining upper bits are all "0" or
all "1" has continued about for 300ms, zero data is detected. Zero data detection is performed independently
for the left and right channels.
Mute flag output
The LMUT and RMUT pins go active when any one of the following conditions is met.
The polarity can be selected with the ZDPL command of $9X.
When zero data is detected
When a high signal is input to the SYSM pin
When the SMUT command of $AX is set
Attenuation operation
Assuming the attenuation commands X1, X2 and X3, the corresponding audio outputs are Y1, Y2 and Y3 (Y1
> Y3 > Y2). First, the command X1 is sent and then the audio approaches Y1. When the command X2 is sent
before the audio output reaches Y1 (A in the figure), the audio output passes Y1 and approaches Y2. And,
when the command X3 is sent before the audio output reaches Y2 (B or C in the figure), the audio output
approaches Y3 from the value (B or C in the figure) at that point.
