Codevision Microcontroller with 8K Bytes In-System AT90S8535

The EEPROM is shared between program memory and
data memory, depending on the mode. The portion of
EEPROM dedicated to each function is flexible and varies
according to the application.
Program memory is read-only in normal operation mode.
Both Flash and EEPROM memory locations are directly
addressable. The EEPROM memory locations follow the
Flash memory in the program address space.
Program Memory
The AT90SC microcontroller has separate address spaces
for program memory and data memory. Up to 48K bytes of
Flash program memory are available. Figure 1 shows the
program memory.
