Data Pointer Decrement Feature Simplifies Copy Operation for Overlapping Memory Buffers

Abstract: Memory management can be simplified by using the data pointer decrement feature found in the Maxim high-speed microcontroller family. This application note explores the use of MOVX operations in the DS80C400, DS5250, DS89C430 and other products in this family of microcontrollers. Sample code highlights the DPTR when doing memory transfer operations.
