Identification EEPROM

The SK-AM69 board identified and revision information are stored in an on-board EEPROM. The first 259 bytes of memory are pre-programmed with SK identification information. The format of that data is provided in Table 3-5. The remaining 32509 bytes are available for data or code storage.

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