Running program from both internal and external RAM in FX2LP/FX1

Question: Is it possible in FX2LP/FX1 to run two programs in the same cycle (without much time lapse or a reset) where one is being executed from the internal RAM and the other from the external RAM?

 

Answer:

No, the 8051 in the FX2LP/FX1 is not capable of running programs simultaneously from internal and external RAM.  The programs have to be merged and placed either in internal RAM or external RAM.
