* byte 8 are in their final spots so avr[i], i={0,1} can be and-ed with

|

* places, all second bits but second bit from eight byte are in their places...
|

* only 1 eight bit from eight byte is in it's place). In second loop we do all

* operations symmetrically, in order to get other half of bits in their final
|
