scope:

This Technical Report specifies a series of extensions of the programming language C (as specified by ISO/IEC 9899:1999) to support features commonly found in embedded processors. It deals with the following topics: extensions to support fixed-point arithmetic, named address spaces, and basic I/O hardware addressing.

Each clause in this Technical Report deals with a specific topic. The first subclauses of clauses 4, 5 and 6 contain a technical description of the features of the topic. These subclauses provide an overview but do not contain all the fine details. The last subclause of each clause contains the editorial changes to ISO/IEC 9899:1999 necessary to fully specify the topic in ISO/IEC 9899:1999, and thereby provides a complete definition. Additional explanation and rationale are provided in the Annexes
