Flash and EEPROM Memory
The EM200 has 128KBytes of flash memory and 2KBytes of EEPROM memory.
Half of the flash memory (64KB) is used to store the TiOS firmware. When you are performing a firmware upgrade it is this memory you are saving the firmware binary into.
The second half of the flash (64KB) is available to your Tibbo BASIC/C application.
The EEPROM is almost fully available to your application, save for a small 8-byte area called "special configuration area". The EEPROM is accessed through the storage (stor.) object (see TIDE, TiOS, Tibbo BASIC, and Tibbo C Manual). Details on the special configuration area are provided in the Platform-dependent Programming Information section inside the EM200 platform documentation (same manual).
