7. Memory
The FO includes three different memories:
•
The Flash EPROM , which permanently stores the factory configuration and the firmware
•
The RAM, where the current configuration is
•
The EEPROM is a non-volatile memory where the 4 user configurations are saved. The content of this memory is protected even when the
unit is switched off.
At the first power-up or after a complete re-initialisation, the content of the three memories is the same and is the factory default configuration.
The AT&Wn command saves the current configuration in the non-volatile memory. All changes made by the user are saved as user
configuration (n=0 to 3)
The last configuration saved by an AT&Wn command will be automatically loaded at the next reset or power-up.
These memory operations are described in the following drawing:
