Bit manipulation in assembly language
WebApr 13, 2001 · Bit manipulation instructions manipulate a specific bit of a bit string (or operand treated as a bit string). Bit clear changes the specified bit to zero. Bit set changes the specified bit to one. Bit change modifies a specified bit, clearing a one bit to zero and setting a zero bit to one. In some processors, the value of the bit before ...
