ANSI 537:2016 pdf free download – Zoned Device ATA Command Set (ZAC)
Quantities having a defined numeric value are identified by large uppercase letters (e.g., the command code in the IDENTIFY DEVICE command). Quantities having a discrete but unspecified value are identified using small uppercase letters (e.g.. . SEQUENTIAL WRITE PREFERRED is one possible value of the Zone Type zone attribute). Such quantities are associated with an observable behavior or value that is specific to a given implementation standard. Names of fields are in small uppercase (e.g., COUNT). Normal case is used when the contents of a field are being discussed. Fields containing only one bit are usually referred to as the NAME bit instead of the NAME field. (See 3.4.5 for the naming convention used for numbering bits.) The expression“word n”” or “bit n”indicates the content of word n or the content of bit n.
3.4.2 Precedence
If there is a conflict between text, figures, and tables, the precedence shall be tables, figures, then text.
3.4.3 Lists
3.4.3.1 Lists overview
Lists are associated with an introductory paragraph or phrase, and are numbered relative to that paragraph or phrase (i.e., all lists begin with an a) or 1) entry). Each item in a list is preceded by an identification with the style of the identification being determined by whether the list is intended to be an ordered list or an unordered list. If the item in a list is not a complete sentence, the first word in the item is not capitalized. If the item in a list is a complete sentence, the first word in the item is capitalized. Each item in a list ends with a semicolon, except the last item, which ends in a period. The next to the last entry in the list ends with a semicolon followed by an“and” or an“or”(i.e., …:. and”, or …. or”). The“and” is used if all the items in the list are required. The“or”is used if only one or more items in the list are required. 3.4.3.2 Unordered lists An unordered list is one in which the order of the listed items is unimportant
3.4.4 Numbering
A binary number is represented in this standard by any sequence of digits consisting 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 standard by any sequence of digits consisting 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 between characters in hexadecimal number representations to increase readability or delineate field boundaries (e.g., B FD8C FA23h or B_ FD8C_ FA23h). A decimal number is represented in this standard by any sequence of digits consisting of only the Arabic numerals 0 through 9 not immediately followed by a lower-case b or lower-case h (e.g., 25). This standard uses the following conventions for representing decimal numbers:
a) the decimal separator (i.e., separating the integer and fractional portions of the number) is a period;
b) the thousands separator (i.e, separating groups of three digits in a portion of the number) is a space; and
c) the thousands separator is used in both the integer portion and the fraction portion of a number. Table 1 shows some examples of decimal numbers using various numbering conventions.
