Preliminary

TS80C31X2

6.2 Dual Data Pointer Register Ddptr

The additional data pointer can be used to speed up code execution and reduce code size in a number of

ways.

The dual DPTR structure is a way by which the chip will specify the address of an external data memory

location. There are two 16-bit DPTR registers that address the external memory, and a single bit called

DPS=AUXR1/bit0(SeeTable5.)thatallowstheprogramcodetoswitchbetweenthem(RefertoFigure 3).
