MERGE_BITS— Merge of bits under mask
MERGE_BITS(I, J, MASK)merges the bits of I and J as determined by the mask. The i-th bit of the result is equal to the i-th bit of I if the i-th bit of MASK is 1; it is equal to the i-th bit of J otherwise.
RESULT = MERGE_BITS(I, J, MASK)
|I||Shall be of type |
|J||Shall be of type |
|MASK||Shall be of type |
