You need to do the Bitwise AND (&) / Bitwise OR (|) to do the masking Truth table is as follows OR Code: +-----+-----+-----+ | OP1 | OP2 | O/P | +-----+-----+-----+ | 0 | 0 | 0 | | 0 | 1 | 1 | | 1 | 0 | 1 | | 1 | 1 | 1 | +-----+-----+-----+ AND Code: +-----+-----+-----+ | OP1 | OP2 | O/P | +-----+-----+-----+ | 0 | 0 | 0 | | 0 | 1 | 0 | | 1 | 0 | 0 | | 1 | 1 | 1 | +-----+-----+-----+ Or it with all Zeros and you get the the masked digit or AND it with 1.
