Manual Conventions
The following manual conventions provide clarity and ease of use.
Notations specific to assembly language, address operands, opcodes, and instruction
descriptions are explained in the chapters discussing those topics.
Courier Typeface
User-typed commands, code lines and fragments, bit names, equations, hexadecimal
addresses, and executable items are distinguished from general text by the use

of the Courier typeface. Where the use of the font is not indicated (for example, Index)
the name of the entity is presented in upper case.
For example, Internal RAM begins at FFFF_0000H .
Binary Values
Binary values are designated by an uppercase ‘B’ suffix. For readability, underscore ‘_’
characters separate large values into four-digit groups, except in program statements.
For example, 8-bit binary value 0100_0010B .
Hexadecimal Values
Hexadecimal values are designated by an uppercase ‘ H ’ and appear in the Courier type-
face. For readability, underscore ‘_’ characters separate large values into four-digit groups,
except in program statements as illustrated in the below examples:
