CMU IRQ Handler
void DMA_IRQHandler | ( | void |
|
) |
Interrupt handler for the DMA cycle completion handling.
DMA IRQ Handler
Clears any pending flags and calls registered callback (if any).
If using the default interrupt vector table setup provided, this function is automatically placed in the IRQ table due to weak linking. If taking control over the interrupt vector table in some other way, this interrupt handler must be installed to support callback actions.
For the user to implement a custom IRQ handler or run without a DMA IRQ handler, define EXCLUDE_DEFAULT_DMA_IRQ_HANDLER with a #define statement or with the compiler option -D.

uint32_t SystemCoreClockGet | ( | void |
|
) |
Get the current core clock frequency.
Calculate and get the current core clock frequency based on the current configuration. Assuming that the SystemCoreClock global variable is maintained, the core clock frequency is stored in that variable as well. This function will however calculate the core clock based on actual HW configuration. It will also update the SystemCoreClock global variable.
- Note
- This is an EFM32 proprietary function, not part of the CMSIS definition.
- Returns
- The current core clock frequency in Hz.

Update CMSIS SystemCoreClock variable.
CMSIS defines a global variable SystemCoreClock that shall hold the core frequency in Hz. If the core frequency is dynamically changed, the variable must be kept updated in order to be CMSIS compliant.
Notice that if only changing core clock frequency through the EFM32 CMU API, this variable will be kept updated. This function is only provided for CMSIS compliance and if a user modifies the the core clock outside the CMU API.

Set high frequency crystal oscillator clock frequency for target system.
- Note
- This function is mainly provided for being able to handle target systems with different HF crystal oscillator frequencies run-time. If used, it should probably only be used once during system startup.
- This is an EFM32 proprietary function, not part of the CMSIS definition.
- Parameters
-

Initialize the system.
Do required generic HW system init.
- Note
- This function is invoked during system init, before the main() routine and any data has been initialized. For this reason, it cannot do any initialization of variables etc.
