	  PREDIV is PLLSCR clock signal prescaler, present on STM32F0 SoC having
	  an HSE Oscillator available like the stm32f04xx, stm32f07xx,
	  stm32f09xx and stm32f030xc parts. If configured on a non supported
	  part, the HSI oscillator will be used a default PLL source and this
	  config will be ignored.
