EMU IRQ Handler

The EMU_IRQHandler provided by TEMPDRV will call TEMPDRV_IRQ_Handler. Configure EMU_CUSTOM_IRQ_HANDLER = true if the application wants to implement its own EMU_IRQHandler. This is typically needed if one of the non-temperature related EMU interrupt flags are in use.

static __INLINE uint32_t SystemCoreClockGet ( void )

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 only if changing the core clock frequency through the EMLIB 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 EMLIB CMU API.

uint32_t SystemHCLKGet ( void )

Get the current system core clock frequency (HCLK).

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 a EFR32MG22 specific function, not part of the CMSIS definition.
Returns
The current core clock (HCLK) frequency in Hz.
