Device Initialization

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

Functions

void BSP_initBoard (void)
Initialize board based on HAL configuration.
void BSP_initClocks (void)
Initialize crystal oscillators and configure clock trees.
void BSP_initDcdc (void)
Configure and initialize the DC-to-DC converter.
void BSP_initDevice (void)
Initialize the device using HAL config settings.
void BSP_initEmu (void)
Configure EMU energy modes.
