P89V52X2
80C51 with 256 B RAM, 192 B data EEPROM
6.5 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 8).

AO
ALE off: disables/enables ALE. AO = 0 results in ALE emitted at a
constant rate of 1
2 the oscillator frequency. In case of AO = 1, ALE is
active only during a MOVX or MOVC.
