37 //!
38 //! The CPU API provides a set of functions performing very low-level control of the system CPU.
39 //! All functions in this API are written in assembler in order to either access special registers
40 //! or avoid any compiler optimizations. Each function exists in several compiler specific versions:
41 //! One version for each supported compiler.
