Numbers in decimal notation are represented by the digits 0 to 9. The decimal symbol is “,” (comma). In large numbers the “ ” (space) can be used as digit grouping symbol. Numbers in hexadecimal notation are represented by the hexadecimal digits 0 to 9 and A to F in parentheses or followed by lowercase “h”. The character x in hexadecimal numbers represents any digit 0 to 9 or A to F. Numbers in binary notations and bit patterns are represented by strings of digits 0 and 1, with the most- significant bit shown to the left. The character x in binary numbers represents a digit 0 or 1. Negative values of numbers in binary notation are given as two’s complement. In a pattern of n bits, bit b (n–1) shall be the most-significant bit (msb) and bit b 0 shall be the least-significant bit (lsb). Bit b (n–1) shall be recorded first. An uninterrupted sequence of m 0’s in a bit pattern can be represented by [0 m ]. The setting of bits is denoted by ZERO and ONE. In data fields composed of bytes, the data is recorded so that the Most-Significant Byte (MSB), identified as Byte 0, shall be recorded first and the Least-Significant Byte (LSB) last. In a field of 8n bits, bit b (8n–1) shall be the most-significant bit (msb) and bit b 0 the least-significant bit (lsb). Bit b (8n–1) shall be recorded first. In data fields composed of nibbles, the data is recorded so that the most-significant nibble, identified as Nibble 0, shall be recorded first and the least-significant nibble last. In a field of 4n bits, bit b (4n–1) shall be the most-significant bit (msb) and bit b 0 the least-significant bit (lsb). Bit b (4n–1) shall be recorded first. A range of values is indicated as x ~ y, where x and y are included in the range. A list of integers is indicated as i .. j. The list contains all numbers between i and j, including i and j (e.g. k = 0 .. 7). If the step size is different from 1, this is indicated as: i, (i+step) .. j (e.g. k = 1, 4 .. 16, where step=3). A group of parameters is indicated as Param m..n or P m .. P n .
