What precautions should be taken when using EEPROM?
1. EEPROM control pin must be pulled up with resistor, the recommended resistance
value is 1K.
2. User must make sure the feed back signal ACK is correct, it can not be ignored, otherwise, it will easily lead to read and write errors.
3. For important data, such as calibration data, user should give checksum protection and backup in different locations to avoid data loss because of EEPROM malfunction.
