This section describes advanced programming information that experienced software engineers will find invaluable. Knowledge of most of these topics is not necessary to successfully create an embedded C16x/ST10 target program using the C166 Compiler. However, the following sections provide insight into how many non-standard procedures can be accomplished.
This section discusses the following topics:
- Files you may alter to customize the startup procedures.
- Files you may alter to customize run-time execution of several library routines.
- The conventions the C166 Compiler uses to name code and data segments.
- How to Interface the C166 functions to assembly routines.
- Data storage formats for different C166 data types.
- Different optimizing features of the C166 optimizing compiler.
