System Clock Selection
• Switching from Low to High speed or from High to Low speed system
clock, it is recommended to use a transition state with a medium speed
clock for at least 1us.
• Clock source switching conditions:
• Switching from HSE or HSI or MSI to PLL with AHB frequency ( HCLK) higher than
80MHz.
• Switching from PLL with HCLK higher than 80MHz to HSE or HSI or MSI
• Transition state:
• Set the AHB prescaler HPRE[3:0] bits to divide System frequency by 2
• Switch system clock to PLL
• Reconfigure AHB prescaler bits to needed HCLK frequency

In STM32L4+ Series devices, it is recommended to use a
transition state while switching from Low to High speed or
from High to Low speed system clock. This slide presents
the recommended sequence for the transition state.
