2.7.6 Identification EEPROM

The EVM board identified and revision information are stored in an on-board EEPROM. The first 259 bytes of memory are pre-programmed with EVM identification information. The format of that data is provided in the table below. The remaining 32509 bytes are available for data or code storage.

The EEPROM is accessible from WKUP I2C0 port of processor at address 0x51.
