WebThe logical operations are essentially the same as the corresponding boolean operators operating on individual bits of the register. The BIC (Bitwise bit Clear) instruction performs an AND of the register that is the first after the destination register, with the inverted value of the second operand. For example, to clear bit [11] of register X0, use:

Webnot d,s # load register d with the # bitwise not of register s # (pseudoinstruction) This is a pseudoinstruction. The assembler translates it into a single basic assembly instruction, a nor instruction. The nor operation is given in the table. The nor of two bits is equivalent to applying not to the or of the WebTo multiply a sixteen bit number by two, we first LSL the lower byte, then ROL the high byte, this has the net effect of "rolling" the high bit of the lower byte into the first bit of the 2nd byte. This technique can be expanded to multiply even larger numbers. Multiplying a 32-bit number by two: how do i find my tls version
