BUS<b>:I2S:FOFFset <FrameOffset>
Sets a delay of the channel blocks after the frame start (word select edge). Thus, all
channels are shifted.
Suffix:

.
1..4
Parameters:
<FrameOffset> *RST: 0
Default unit: Bit
BUS<b>:I2S:WLENgth <WordLength>
Defines the number of bits in an audio data word (receiver length).
Suffix:
<b>
.
1..4
Parameters:
<WordLength> Range: The minimum length is 1bit, the maximum length is
the channel length.
*RST: 8
Default unit: Bit
BUS<b>:I2S:WSELect:POLarity <WordSelectPolarity>
For I²S, left and right justified signals (BUS<b>:I2S:AVARiant is set to I2S/LJ/RJ),
the polarity defines the word select values assigned to the left and right channels.
For TDM signals (BUS<b>:I2S:AVARiant is set to TDM), the polarity defines the
edge of the frame synchronization pulse that identifies the beginning of a frame.
Suffix:

1..4
Parameters:
<WordSelectPolarity> NORMal | INVert
NORMal
0 indicates the left channel, and 1 indicates the right channel.
This is the usual setting.
TDM: the frame begins with a rising edge. This is the usual set-
ting.
