4233H–8051–02/08
Dual Data Pointer
Register (DPTR)
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 exter-
nal 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 3.) that allows the pro-
gram code to switch between them (Refer to Figure 3).
Figure 3. Use of Dual Pointer
Table 3. AUXR1: Auxiliary Register 1
Notes: 1. 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.
2. GF3 will not be available on first version of the RC devices.
