7.2 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 4.) that allows the program code to switch between them (Refer to Figure 3).
Figure 3. Use of Dual Pointer
Table 4. AUXR1: Auxiliary Register 1
Application
Software can take advantage of the additional data pointers to both increase speed and reduce code size, for
example, block operations (copy, compare, search ...) are well served by using one data pointer as a ’source’
pointer and the other one as a "destination" pointer.

Not implemented, reserved for future use.a
a.
User software should not write 1s to reserved bits. These bits may be used in future 8051 family
products to invoke new feature. In that case, the reset value of the new bit will be 0, and its active
value will be 1. The value read from a reserved bit is indeterminate.
b.
GF3 will not be available on first version of the RC devices.
