1.4 Conventions
Certain words and terms used in this manual have a specific meaning beyond the normal English meaning. These words and
terms are defined either in this clause or in the text where they first appear. Names of commands, status codes, sense keys, and
additional sense codes are in all uppercase (e.g., REQUEST SENSE).
If there is more than one CDB length for a particular command (e.g., MODE SENSE(6) and MODE SENSE(10) and the name of the
command is used in a sentence without any CDB length descriptor (e.g., MODE SENSE), then the condition specified in the
sentence applies to all CDB lengths for that command.
Names of fields and state variables are in uppercase (e.g. NAME). When a field or state variable name contains acronyms,
uppercase letters may be used for readability. Normal case is used when the contents of a field or state variable are being
discussed. Fields or state variables containing only one bit are usually referred to as the NAME bit instead of the NAME field.
Normal case is used for words having the normal English meaning.
A binary number is represented in this manual by any sequence of digits comprised of only the Western-Arabic numerals 0 and 1
immediately followed by a lower-case b (e.g., 0101b). Underscores or spaces may be included between characters in binary
number representations to increase readability or delineate field boundaries (e.g., 0 0101 1010b or 0_0101_1010b).
A hexadecimal number is represented in this manual by any sequence of digits comprised of only the Western-Arabic numerals
0 through 9 and/or the upper-case English letters A through F immediately followed by a lower-case h (e.g., FA23h). Underscores
or spaces may be included in hexadecimal number representations to increase readability or delineate field boundaries (e.g., B
FD8CFA23h or B_FD8C_FA23h).
A decimal number is represented in this manual by any sequence of digits comprised of only the Western-Arabic numerals 0
through 9 not immediately followed by a lower-case b or lower-case h (e.g., 25).
When the value of the bit or field is not relevant, x or xx appears in place of a specific value.
This manual uses the ISO convention for representing decimal numbers (e.g., the thousands and higher multiples are separated
by a space and a comma is used as the decimal point). Table 1 shows some examples of decimal numbers represented using the
ISO and American conventions.

Lists sequenced by letters (e.g., a) red, b) blue, c) green) show no ordering relationship between the listed items. Lists sequenced
by numbers (e.g., 1) red, 2) blue, 3) green) show an ordering relationship between the listed items.
If a conflict arises between text, tables or figures, the order of precedence to resolve the conflicts is text, then tables, and finally
figures. Not all tables or figures are fully described in the text. Tables show data format and values. Notes do not constitute any
requirements for implementors.
