Macros

•Macro names must be all uppercase

•Words shall be separated by an underscore

•The letter ‘m’ in lowercase is used as a prefix to specify that it is a macro, then the device abbreviation must appear

•Example: mSUNI4x622_GET_BIT is a valid name for a macro

Constants

•Constant names must be all uppercase

•Words shall be separated by an underscore

•The device abbreviation must appear as a prefix

•Example: SUNI4x622_MAX_POLL is a valid name for a constant

Structures

•Structure names must be all uppercase

•Words shall be separated by an underscore

•The letter ‘s’ in lowercase must be used as a prefix to specify that it is a structure, then the device abbreviation must appear

•Example: sSUNI4x622_DDB is a valid name for a structure
