Data pointer in the 8051 microcontrollers is one of the storage registers. Other storage registers in an 8051 microcontroller are the accumulator, the stack pointer (SP), R register, B register and the program counter (PC). The Data Pointer in 8051 microcontrollers in short form DPTR is the only 2-byte register a user can access. Other registers like the B register and accumulator are 1-byte register. This data pointer just like the name implies is for data pointing. With it, the 8051 can access memory outside the system.
