Read/Write Mode Control
Only available to set 0 for Read back mode.
ZFGx
Zero Detection Flag
When x = L or R, corresponding to the DAC output channel.
These bits are Read only.
Default Value: 00
ZFGx = 0
ZFGx = 1
Not ZERO
ZERO Detected
When the PCM1738 detects that audio input data is continuously zero for 1024f
S
, the ZFGx bit is set to 1 for
the corresponding channel(s). Zero detect flags are also available at ZEROL (pin 2) and ZEROR (pin 3).
