Abstract
This arrangement permits a central processing unit, which can differentiate between code and data fetches, to execute code from any number of pages of data memory without loss of access capability to any of the corresponding pages of program code memory. The page of data memory, corresponding to the program code memory page containing the control transfer programs, may not contain executable programs.
