First Channel
Defines if the left or the right channel is the first channel in the frame.
The setting is available for I²S standard, left and right justified audio signals.
Remote command:
BUS<b>:I2S:CHANnel:ORDer on page 668
No. of Channels
Sets the number of channels transmitted on the TDM audio line.
Remote command:
BUS<b>:I2S:CHANnel:TDMCount on page 668
Channel Delay
Sets a delay of the channel blocks after the frame start (word select edge). Thus, all
channels are shifted.
The setting is available only for TDM signals.

Channel Offset
Sets the number of bits between the channel start and the start of the audio word. The
setting is available for left justified data format and TDM audio signals.
For TDM, possible values depend on the channel length and the word length. The
maximum offset is Channel length - Word length. If you change the channel length or
the word length, the channel offset is adjusted automatically.
Remote command:
BUS<b>:I2S:CHANnel:OFFSet on page 668
Word Length
Defines the number of bits in an audio data word (receiver length). The minimum
length is 1 bit, the maximum length is the channel length.
Remote command:
BUS<b>:I2S:WLENgth on page 671
