Description
This register is used to set the value of the status
bit in the IEC958 data stream.
SFR
: 44.1KHz sampling frequency bit
PRE
: Preemphasis data bit
COP
: Copy bit
COM
: Compress data bit
This bit must be set to one in com-
pressed mode and must be clear in
non compressed mode.

Description
In “compressed” mode, a burst of null data is sent
when there is no more data to transmit (due to an
error or a gap in the incoming bit-stream). This
register is used to set the length of the burst. The
length of the burst in “IEC958 sub-frame” unit. The
length of the burst is (n+1), where n is the content
of this register. This register must always be load-
ed with an odd value. We recommend to set this
register to “7”.

Description
After a soft or hard reset the decoder is in idle
mode. The decoder stays in this mode until the
register “RUN” is set. In run mode the decoder
takes into account the state of all the configuration
registers and begins to decode.
