WebThe 8086 microprocessor supports 8 types of instructions − ... CMC − Used to put complement at the state of carry flag CF. STD − Used to set the direction flag DF to 1. CLD − Used to clear/reset the direction flag DF to 0. STI − Used to set the interrupt enable … 8086 was the first 16-bit microprocessor available in 40-pin DIP (Dual Inline … WebOn the other hand, the operation performed by the last instruction, complement carry (CMC), cannot be expressed in terms of the CLC and STC instructions. Therefore, it is the independent instruction. 6- Compare instruction An instruction is included in the instruction set of the 8086 that can be used to compare two 8-bit or 16-bit numbers.
WebDec 1, 2024 · There is some info regarding the algorithm how the instruction works: if low nibble of AL > 9 or AF = 1 then: AL = AL + 6 AH = AH + 1 AF = 1 CF = 1 else AF = 0 CF = 0 in both cases: clear the high nibble of AL. Example: MOV AX, 15 ; AH = 00, AL = 0Fh AAA ; AH = 01, AL = 05 RET Web1 Answer Sorted by: 1 I've successfully converted the decimal to binary, but now I need to convert it back to decimal.
