Notation
Description
ASCII
Indicates the entry conforms to the American Standard Code for Information Interchange definition of
character (text) information.
Binary
Indicates the entry is a raw, numeric value.
Hex
Indicates hexadecimal notation. This is used with both ASCII characters (0 – 9, A – F) and numeric values.
BCD
Indicates the entry is a numeric value where each four bits represents a decimal digit.
FPn
Indicates the entry is the ASCII representation of a floating-point number with n places following the
decimal point.
<n>
Indicates a single 8-bit byte. When the contents are numeric, it indicates a hexadecimal numeric value; i.e.
<84> represents hexadecimal 84 (132 decimal). When the contents are capital letters, it represents a
named ASCII control character; i.e. <SP> represents a space character, <CR> represents a carriage return
character and <LF> represents a line feed character.
MSB
Most Significant Byte of a multi-byte value.
MSbit
Most Significant Bit of a binary number.
LSB
Least Significant Byte of a multi-byte value.
