Program Memory Areas

The XC2000 provides two on-chip program memory areas for code/data storage:

•The Program Flash/ROM stores code and constant data. Flash memory is (re-)

programmed by the application software or flash loaders, ROM is mask-programmed

in the factory.

•The Program SRAM (PSRAM) stores temporary code sequences and other data.

For example higher level boot loader software can be written to the PSRAM and then

be executed to program the on-chip Flash memory.
