DOCUMENT ASSUMPTIONS AND CONVENTIONS
UM001001-1000
The following assumptions and conventions have been adopted to provide
clarity and ease of use:
•
The words set and clear imply that a register bit or a condition has the
value of logical 1 and logical 0 respectively. When the terms set and clear
are followed by a number, often in parentheses, the word logical may not
be included, but it is implied.
•
A field of bits within a register are designated as: Register (n..n). For
example:
Bus
designated as:
Registern..Registern. For example: OPBCS5..OPBCS0.
•
In this document, the terms LSB and MSB mean least significant bit and
most significant bit respectively.
•
Commands, code lines and fragments, register and other mnemonics,
values, equations, and various executable items are distinguished from
general text by the use of the Courier font. This convention is not used
within tables. Where the use of the font is not possible, as in the Index, the
name of the entity is capitalized. For example: The STP bit in the
register must be
