3.5 Dual Data Pointers
The device has two 16-bit data pointers. The DPTR Select (DPS) bit in AUXR1 determines which of the two data
pointers is accessed. When DPS=0, DPTR0 is selected; when DPS=1, DPTR1 is selected. Quickly switching
between the two data pointers can be accomplished by a single INC instruction on AUXR1. (See Figure 3-5)

3.6 Special Function Registers
Most of the unique features of the FlashFlex51 microcontroller family are controlled by bits in special function regis-
ters (SFRs) located in the SFR memory map shown in Table 3-4. Individual descriptions of each SFR are provided
and reset values indicated in Tables 3-5 to 3-9.
