Device InitializationBSP
Detailed Description
Device Initialization using HAL configuration.
The BSP Device Initialization APIs provide functionality to initialize the device for a specific application and board based on a HAL configuration header file. The BSP Device Initialization module provides APIs that perform
- EFM32/EZR32/EFR32 errata workaround
- DC-to-DC converter initialization on devices with DCDC
- Clock initialization for crystal oscillators and clock selection for HF and LF clock trees
