XMC1302 Low Power Modes

Hi,

The following code places the device in the lowest power mode (~250uA according to data sheet)
Code:

  // The clock of the peripherals that are not needed during sleep state can be gated before entering sleep state
  XMC_SCU_CLOCK_GatePeripheralClock(XMC_SCU_PERIPHERAL_CLOCK_MATH);

  // Enable FLASH power down during SLEEP and DEEPSLEEP mode
  XMC_SCU_CLOCK_EnableFlashPowerDown();

  // Make sure that SLEEPDEEP bit is set
  SCB->SCR |= SCB_SCR_SLEEPDEEP_Msk;

  // Return to SLEEP mode after handling the wakeup event
  SCB->SCR |= SCB_SCR_SLEEPONEXIT_Msk;

  // in deep-sleep state, the PCLK and MCLK will
  // be switched to a slow standby clock and DCO1 will be put into power-down mode
  // It is recommended to slow down the PCLK and MCLK before entering deep sleep
  // mode to prevent a sudden load change that could cause a brownout reset.
  XMC_SCU_CLOCK_SetFastPeripheralClockSource(XMC_SCU_CLOCK_PCLKSRC_MCLK);
  XMC_SCU_CLOCK_SetMCLKFrequency(125);

  /* Placeholder for user application code. The while loop below can be replaced with user application code. */
  while(1U)
  {
        // Put system in DEEPSLEEP state
        __WFI();
  }
