Slaves are always allocated memory starting with the seven
rightmost bytes in the word. Even slaves that require just one
byte of I/O memory will be allocated one word.
Example:

If there are slaves that require just one byte of I/O memory,
they are allocated the rightmost seven bits or leftmost seven
bits so that the total number of occupied words is minimized.
Example:
