Macro Definition Documentation

#define BSPACM_CORE_DEEP_SLEEP

Value:

do {   \
    EMU_EnterEM2(true);                 \
    SCB->SCR &= ~SCB_SCR_SLEEPDEEP_Msk; \
  } while(0)

Bypass default implementation in favor of EFM32 standard, invoked in a way that causes it to restore clock configurations, and augmented by clearing the SLEEPDEEP bit which EMU_EnterEM2() leaves set.

Function Documentation

void vBSPACMdeviceEFM32setupSWO

(

void

)

Function to turn on the EFM32 Serial Wire Output (SWO) feature, required when using the Trace Port Interface Unit to feed back PC sample and interrupt information to the energyAware Profiler application.

Note

SWO is only available on Cortex-M3 and Cortex-M4 device lines, not on the Zero Gecko.
