PLLHSEPRES
HSE prescaler for PLL input
Set and cleared by software to divide HSE before PLL entry. This bit can only be
written when PLL is disabled.
0: HSE clock not divided
1: HSE divided by 2
16
PLLSRC
PLL clock source
Set and cleared by software to select PLL clock source. This bit can only be
written when PLL is disabled.
0: HSI clock divided by 2 is used as the PLL input clock
1: HSE clock selected as PLL input clock
