Force page paging scheme for microcontrollers of various sizes using data random access memory

摘要

A microcontroller architecture that adds a dedicated bit in the op-code decode field to force data access to take place on a page of the random access memory (RAM) for that instruction. This allows the user to have any page selected and still have direct access to the special function registers or the register variables that are located on a pre-defined page of the RAM. The setting of the dedicated bit will not affect the current operation of the microcontroller nor will the setting of the bit modify the currently selected address stored in a page select register currently being used by the microcontroller.
