6.5 Central Accelerometer Driver
The Central Accelerometer Driver (ACC) is created as a separate software module. The main advantage is full HW abstraction and API
independence used in the MCU family. The driver API covers the entire functionality of the main accelerometer, which means all
accelerometer functionality can be controlled using API functions.
The ACC Driver is dependent on the BSD layer (basic SPI driver), and on the GPIO driver (General Purpose Input/Output), which provides
basic functions for controlling input/output MCU pins.
