2.1.3.21.3 I2C Signal Mapping
"The expansion connector provides all I2C interfaces of the phyCORE-OMAP44xx as well as the I2C interfaces
intended for camera connectivity. All signals have been translated from 1.8 V to 3.3 V or VCC_CAM-1/2 by
voltage-level translators on the carrier board. Please pay special attention to the Signal Level (SL) column in
the following table when connecting other devices to these I2C interfaces."
2.1.3.21.4 Primary Camera Interface CSI2-A/CSI21 Signal Mapping
The expansion connector X5 provides the CSI2-A/CSI21 camera interface of the phyCORE-OMAP44xx.
