I2C Serial EEPROM
This section describes the I2C Serial EEPROM on the THDB-SUM board
The THDB-SUM board provides an EEPROM (U10) which can be configured by the I2C interface. The size of
the EEPROM is 128 bit that can store the board information or user’s data. The detailed pin description
between EEPROM and HSMC connector is listed in the
Table 3.12
