Web6 apr. 2024 · The 8051 Microcontroller four Ports which can be used as Input and/or Output. These four ports are P0, P1, P2 and P3. Each Port has a corresponding register with same names (the Port Registers are also P0, P1, P2 and P3). The addresses of the Port Registers are as follows: P0 – 80H, P1 – 90H, P2 – A0H and P2 – B0H. WebSpecial function registers are upper RAM in the 8051 microcontrollers. These registers contain all peripherally related registers like P0, P1, P2, P3, timers or counters, serial port, and interrupts-related registers. The SFR memory address starts from 80h to FFh. The SFR register is implemented by bit-address registers and byte-address registers.
