HAL Layer firmware overview

This section describes the hardware abstraction layer function used by the upper API layer

described in the previous section. All the library microcontroller hardware dependent

functions and related defined types are described in this section. See Figure 2.

The final application should NEVER directly use these HAL functions, and it should manage

the STLM75 temperature sensor through the API layer functions as described above.
