4.1.8 Aardvark Connector (J9)

This connector matches the Total Phase® Aardvark that allows the user to access the I2C pins on the TPS65994EVM using the I2C Master capabilities. U6 is used to swap between I2C1 or I2C3 connected to the aardvark connector. S3 is used to control which way the 2 to 1 MUX will be set. If S3 is disabled, by default, I2C1 would be connected to the Aardvark header. When S3 is enabled, I2C3 would be connected to the Aardvark header.
