liability for the use of this product in any end application” 0x00

Program EEPROM

The Micro RWD has some internal EEPROM for storing system parameters such as

passwords and authorised identity codes. This command sequence allows individual bytes of

the EEPROM to be programmed with new data. Note that due to the fundamental nature of

these system parameters, incorrect data may render the system temporarily inoperable.
