AT24 Serial EEPROM
==================
A AT24C512 Serial EEPPROM was used for tested I2C. There are other I2C/TWI
devices on-board, but the serial EEPROM is the simplest test.
The Serial EEPROM was mounted on an external adaptor board and connected to
the SAMA5D3x-EK thusly:
- VCC -- VCC
- GND -- GND
- TWCK0(PA31) -- SCL
- TWD0(PA30) -- SDA
By default, PA30 and PA31 are SWJ-DP pins, it can be used as a pin for TWI
peripheral in the end application.
