: Line idle state level. The state of the
interface when the interface is off.
DIV[4:0] : This field is the PCMCLK divider. It
must be set according to the formula:
In 16 bit mode:
IECDIV=(1+PCMDIV)/2-1
In 32 bit mode:
IECDIV=PCMDIV
The table below shows the relationship between
the value of the IEC divider and the value of the
PCM divider described in Section 5.4.3.

“Off”
mode
The IEC958 is not working, the out-
put line is idle. The value of the out-
put line is determined by the value of
bit 5 of the register IEC958_CONF.
The line can be stuck to VDD or to
GND.
“Muted” mode: The outputsare PCM
null data.
“PCM” mode: The outputs are PCM
data. Only the first two decoded
channels (Left and Right) are trans-
mitted.
“Encoded”: The compressed bit-
stream is transmitted (See IEC1937
standard)
