List of sfrs in 8051
WebThe 8051 uses 8 general-purpose registers R0 through R7 (R0, R1, R2, R3, R4, R5, R6, and R7). These registers are used in instructions such as: ADD A, R2 ; adds the value contained in R2 to the accumulator Note since R2 happens to be memory location 02h in the Internal RAM the following instruction has the same effect as the above instruction. WebChapter 4 gives the details of 8051 timer/counters and its related SFRs- TCON & TMOD. Fifth chapter discusses the basic of serial communication and the SFRs-SCON & SBUF used for communication. Input devices (switch, TWS, KB) and output devices (LED, 7-segment display, LCD, relay, DC and stepper motor, optocoupler) interfacing is …
