The description in the manual w ill alw ays be structured in the same
way. The top most description (in this case not used) is always the
least-significant bit, or right-most bit. As you move down the list of
descriptions, you advance to the left on the bit-encoded word. Any
unused bits will be identified, but unused bits will nave no
description. This is why a 16-bit word may only have a few
descriptions. The rest are reserved for future expansion.
When a bit-encoded parameter is viewed in its associated group, it is
actually displayed as a hexadecimal number. The right-most four
bits represent the right-most hexadecimal digit. Each subsequent
group of 4 represents the next hexadecimal digit.
Table B.2 below illustrates the relations hip.

When you display a specific bit-encoded parameter, or choose to
modify a bit-encoded parameter, it will be displayed in bit format,
with an individual description of each bit (see Table B.3). When
modifying a parameter, selecting the bit parameter will allow it to be
altered.
