+	<div class=tooltipinfo>
+	<p>Control the TLV320AIC3206 chip that is at the heart of the Tympan audio interface.
+		The TLV320AIC3206 is used in slave mode, where Teensy controls
+		all clocks and I2S timing in order to get the audio data to and from the chip.

+	<p>This object has no audio inputs or outputs.  Separate i2s objects
+		are used to send and receive audio data.  I2S master mode objects
+		must be used, because this object configures the TLV320AIC3206 in slave
+		mode, where it depends on Teensy to provide all I2S clocks.
+		This object controls
+		how the TLV320AIC3206 will use those I2S audio streams.</p>
