The I
2
C interfaces of the phyCORE-OMAP44xx are available at different connectors on the phyCORE-OMAP44xx
Carrier Board. The following table provides a list of the connectors and pins with I
2
C connectivity. The voltage
level of some of the I
2
C interfaces are translated to a higher level by level shifters on the carrier board.
The following table itemizes the I
2
C interfaces, the connector where they can be found, and the voltage level.
To avoid any conflicts when connecting external I
2
C devices to the phyCORE-OMAP44xx Carrier Board the
addresses of the on-board I
2
C devices must be considered. Some of the addresses can be configured by jumper.
