It is also possible to “reclassify” the Flash memories during runtime, moving the memories
between XDATA memory space and program memory space on-the-fly. This essentially
means that the user can override the initial setting during run-time by writing to a csiop
register (the VM Register). This is useful for IAP, because standard 8051 architecture does
not allow writing to program space. For example, if the user wants to update firmware in
Main Flash memory that is residing in program space, the user can temporarily “reclassify”
the Main Flash memory into XDATA space to erase and rewrite it while executing IAP code

Secondary Flash into program space for systems that need a large amount of Flash for
data recording or large look-up tables, and not so much Flash for 8032 firmware.
