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.
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.
• Bit fields can be manipulated without masking
• Flexibility to access a register as a whole or by bits
• Auto-complete field names in CCStudio
• View in CCStudio watch window just like variable

Level 3 – API Drivers
The peripheral API drivers are a high-level library of
functions that wrap common tasks into parameter-based
functions.
• C call-able functions that automatically set register
bit fields
• Further reduces learning curve for new programmers
• Common tasks and peripheral modes supported

Level 4 – Framework
Built primarily upon the bit field headers, the framework
represents a system template and starting point for all
applications.
• Function-based device initialization, allowing users
to focus on application code
• System management via state machines set to run at
a specific frequency
• Ability to connect to an external GUI via SCI
• Simple switching between RAM and Flash eases early
