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: WebJun 8, 2024 · For bitwise operations that set flags, the negative (N) and zero (Z) flags reflect the result, the carry (C) flag reflects any shifting that occurred during the calculation of op2 (noting that calculating constants may also involve shifting, as noted earlier when we discussed constants), and the overflow (V) flag is unchanged.

Setting individual bits uses the bitwise logical OR. To do this, OR the original value with a binary value of the same size with 1's in all the positions to be set and 0's in all the positions to be left untouched. As an example, the operation below sets bit positions 1, 3, and 5 of the binary value 10010110.

The AND instruction is used for supporting logical expressions by performing bitwise AND operation. The bitwise AND operation returns 1, if the matching bits from both the operands are 1, otherwise it returns 0. For example − The AND operation can be used for clearing one or more bits. For example, say the BL … See more The OR instruction is used for supporting logical expression by performing bitwise OR operation.
