This manual incorporates the following conventions:
Notational
1.
An upper case letter H following a number indicates the number is a
hexadecimal value (e.g., 32 = 20H and 255 = FFH).
hexadecimal value (e.g., 32 = 20H and 255 = FFH).
2.
In this document, a byte is defined as an 8-bit quantity, a word as a 16-
bit quantity, and a double word as a 32-bit quantity.
bit quantity, and a double word as a 32-bit quantity.
3.
This manual represents all memory ordering in the Motorola format.
This means that the least significant byte of a double word is placed in
the most significant memory location. For a further discussion of
memory ordering and information to use Intel ordering, see Chapter 8.

Address Offset - The grey-shaded area on the left is named Address Offset.
Since the structures are double-word wide, these hexadecimal values, added to
the Starting Memory Address, reference the beginning of each double word in
the structure.

Byte Memory Address - The area at the top of the graphic is the Byte Memory
Address. This displays the ordering of byte-wide fields of memory. Each of the
four “Offset + x” fields describes the relationship of byte fields to the Address
Offset.
