EWDS (Erase/Write Disable): After issued, the EEPROM will ignore erase and write commands. To
re-enable erase/write operations issue the EWEN command.
EWEN (Erase/Write Enable): Enables the EEPROM for erase and write operations. The EEPROM
will allow erase and write operations until the “Erase/Write Disable” command is sent, or until power
is cycled.
Note: The EEPROM device will power-up in the erase/write-disabled state. Any erase or write
