# µC/LIB Constant and Macro Library

µC/CPU contains many standard constants and macros. Common constants include Boolean, bit-mask, and integer values; common macros include bit-level, minimum, maximum, and absolute value operations. All µC/LIB constants and macros are prefixed with DEF_ to provide a consistent naming convention and to avoid namespace conflicts with other constants and macros in your application. These constants and macros are defined in lib_def.h .
