  PEAKDETSHUNTOPTMODE=CMD mode after the first enable. This means automatic
  peak detection and shunt current optimization runs at the first call to
  CMU_OscillatorEnable(cmuOsc_HFXO, true, true) or
  CMU_ClockSelectSet(cmuClock_HF, cmuSelect_HFXO) only.
  Optimization can be restarted by calling CMU_OscillatorTuningOptimize(). This is
  required if the temperature changes by more than 100degC.
• Added CMU_HFXOAutostartEnable() function to support automatic HFXO start and
  select.
• Updated default timeouts for CMU_HFXOInit() to optimize HFXO startup
  time. The startup time reduction depends on the oscillator specification.
  The new defaults are safe for typical oscillator specifications.

  configuration depends on RCO band.
• em_emu: Putting DCDC in bypass mode before entering EM4S.
• em_cmu: In the CMU_HFXOInit_TypeDef struct the following members have been
  deprecated and are no longer in use: autoStartEm01, autoSelEm01, and
  autoStartSelOnRacWakeup. Any application using the HFXO autostart feature
  must use the CMU_HFXOAutostartEnable() function instead.
• em_emu: Updating DCDC LP comparator bias thresholds for EM2/3/4 according to
  updated reference manual. The thresholds are compared to the
  em234LoadCurrent_uA value of the EMU_DCDCInit_TypeDef struct.
• em_msc: Fix for errata FLASH_E201 - Potential program failure after power on
  After a flash write the first word is checked to verify write operation. On
  a verification failure the first word is re-programmed.
• em_adc: Enforcing at least 8 cycle aquisition time when reading ADC internal
  temp sensor using a 1.25V reference on platform 2 generation 1 devices.
• em_adc: Setting GPBIASACC when initializing measurement of the ADC internal
  temp sensor as documented in the reference manual.

  init function.

• Added support for WARNSEL, WINSEL and WDOGRSTDIS to em_wdog. Added interrupt
  functions. Added support for multiple WDOG instances. Deprecated functions

  the GPIO_IF register for platform 2 devices.
• Added function GPIO_SlewrateSet() to set slewrate for GPIO ports.
• Added fix for GPIO_E201 in CHIP_Init().
• Added function CMU_HFRCOBandGet() and CMU_HFRCOBandSet() for platform 2.

  and return types are different. Platform 1 and 2 also do not support the same
  HFRCO/AUXHFRCO frequencies.
• Added HFLE wait-state control to CMU_HFRCOBandSet(). This is a bug on
  EFM32 Wonder Gecko only as HFLE DIV4 is required at 24MHz, in between the 28HMz
  and 21MHz HFRCO bands.
• Fixed reset-cause XMASKs for platform 2, gen 1 parts. Improved
  documentation in em_rmu.c.
• Added support for configuring IrDA on USART1 for EFM32 Happy Gecko. The
