I am using stm32f476ZET6 controller. i am use external crystal and internal we use PLL divider but i facing issue regarding PLL clock is not work properly.

[Hiren]

i set system clock 216 Mhz but it is not properly work

also i test same thing set as 54Mhz but same issue faced.

kindly suggest us how to solve this issue
