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 (See Table 5.) that allows the program code to switch between them (Refer to Figure 3).
