4-level Hardware Abstraction Layer
Level 1 – Registers and Addresses
Baseline assembly or C communication to all hardware
registers and addresses. Most MCU vendors stop here.
Level 2 – Bit Fields
At the heart of C2000 software is a set of
memory-mapped bit fields and structures that make
registers and register bits seem like simple variables.

Level 3 – API Drivers
The peripheral API drivers are a high-level library of
functions that wrap common tasks into parameter-based
functions.

Level 4 – Framework
Built primarily upon the bit field headers, the framework
represents a system template and starting point for all
applications.
