8051 instruction
Alphabetical List of Instructions. ACALL - Absolute Call; ADD, ADDC - Add Accumulator (With Carry); AJMP - Absolute Jump; ANL - Bitwise AND; CJNE - Compare and Jump if Not Equal; CLR - Clear Register; CPL - Complement Register; DA - Decimal Adjust; DEC - ,The following pages describe the 8051 instruction set. Instructions are listed in alphabetical order and each is divided into several sections: Description Describes the instruction's effect and describes any arguments. See Also Names related instruct,The 8051 Instruction Set Manual explains the standard 8051 instructions. The 8051 Instruction Set is supported by the Keil Ax51 Macro Assembler and the in-line Assembler of the Keil Cx51 Compiler. This manual contains the following chapters: Architecture ,The INC instruction increments the specified operand by 1. An original value of 0FFh or 0FFFFh overflows to 00h or 0000h. No flags are affected by this instruction. Note When this instruction is used to modify an output port, the value used as the port da,addr 16. 16-bit destination address. Used by LCALL and LJMP. A branch can be anywhere within the 64K byte Program Memory address space. addr 11. 11-bit destination address. Used by ACALL and AJMP. The branch will be within the same 2K byte page of program,The DA instruction adjusts the eight-bit value in the Accumulator resulting from the earlier addition of two variables (each in packed-BCD format), producing two four-bit digits. Any ADD or ADDC instruction may have been used to perform the addition. If A,The following table lists the 8051 instructions by HEX code.
