Absolutely, Martin.

Say your 12 bits is 1001_0110_1110.  If you want to convert it to 16 bits,
high justified, you simply add four bits to the "bottom" (Least Significant
Bit side, right side) and the result is 1001_0110_1110_0000.  That's high
bit justification.  Also, since you now added four bits, the 16 bit number
is 16x larger than the original 12 bit number.

Low bit justification is simply adding the four bits on the "top" (Most
Significant Bit side, left side) and it would be 0000_1001_0110_1110 and the
number would be exactly the same number as you started with, just in a 16
bit realm.

Austin
