STM32h753bit6 HSI clock at startup

[Franksterb92]

tying to find what frequency the hsi is at startup  and normally i search the datasheet for clocks and startup but this returns nothing in the datasheet for the stm32h753bi mcu only thing i see is that it has 4 clocks and it says the hsi is 64mhz is this it

Hello @Franksterb92 

the HSI Clock frequency is indicated, as you said, on the DS12117:
