Tip:  The 2-Wire serial interface can be externally shared with another device. 2-Wire Data Signal
(SAMA5D27 SOM1 Pad 19) and 2-Wire Clock Signal (SAMA5D27 SOM1 Pad 20) are used.
Important:  If the 2-Wire serial interface is used externally, the device connected must have a different I²C
address than the embedded EEPROM. For more details, refer to the device data sheet.
