Registers are small memory elements of size in few byte or word. Registers can be accessed quickly by the ALU (Arithmetic and Logic Unit) of micro controllers.
The DPTR (Data Pointer) register is primarily used in the 8051 microcontroller architecture. It serves as a pointer to access external data memory and is typically utilized in operations involving data transfer between the microcontroller and external RAM or ROM. The DPTR register is 16 bits wide, allowing it to address a larger memory space, and is often used in conjunction with instructions that require data manipulation from external sources.
That depends on the specific microcontroller.
The address range of the Special Function Register (SFR) bank in the 8051 microcontroller architecture typically spans from 0x80 to 0xFF. This range includes various control and status registers used for configuring and managing the microcontroller's operation. Each SFR has a specific function, such as timer control, interrupt management, and I/O port settings. Accessing these registers allows for low-level hardware manipulation and control.
