Remember, the LQD instruction only loads from 16-byte boundaries. It will therefore ignore the four least significant bits during the load, and just load an aligned quadword from memory.
If the number of ones in a byte is already odd, you will set its least significant bit to a zero.
Fill order of the bit within the image bytes: most significant or least significant bit first.
least significant bit
The least significant bit of each block is reserved as the parity bit.
The second selected element selects one of the second groups of voltage references as an output analog voltage according to N-M least significant bits of the N-bit digital signal.
Count the number of ones in each byte of the 8-byte block; if the number of ones is even, make it odd by setting the least significant bit to one.
