Compute the bitwise AND of 128 bits (representing integer data) in a and mask, and set ZF to 1 if the result is zero, otherwise set ZF to 0. Compute the bitwise NOT of a and then AND with mask, and set CF to 1 if the result is zero, otherwise set CF to 0. Return 1 if both the ZF and CF values are zero, otherwise return 0.
