SX/B code to Read and Write to the Internal EEPROM SX28

Good Day to All:
I'm trying to Read and Write·bytes of data to the Internal EEPROM on my SX28 in SX/B.
Not sure I searched the forums correctly since I could not find·any articles on this subject. Please note·I need·the onboard EEPROM, not the external EEPROM. The program needs to store (5) four digit access codes for a keypad lock for a total of 20 bytes of data even if the power is turned off or system is reset.
Thank you confused.gif

    You can READ data with the READ command.

    The SX cannot write to it's internal flash memory. This requires a high voltage that the programmer (SX-Key or SX-Blitz) generates.

    There is a fine line between arrogance and confidence. Make sure you don't cross it...
