An on-board Microchip 24AA32AT device provides an added storage device for factory settings:
- the first 32 bytes of the device are RESERVED: this region stores the bytes for the ConfigID on BORA SOMs configured for booting from NAND device (without NOR SPI on board)
- the device is write protected using the EEPROM_WP
The device has some configuration pins:
- three address pins for configuring the I2C adddress A0, A1, A2 internally configured as A[0..2]='000'
- the EEPROM_WP is connected to J2.78 pin and should not be externally connected
