STM32CubeMX is not allowed to configure clock more than 84MHz for STM32F407VG

Hi,

I use STM32CubeIDE and I use STM32CubeMX configuration tool. Selected device is STM32F407VGTx.

As per datasheet HCLK Max frequency is 168MHz for mentioned device. But STM32CubeMX Clock configuration tool is allowed to set frequency which is more then 84MHz using PLL. i.e. if I select clock frequency 100MHz, its give error of Frequency out of range. I use HSE + PLL and crytal is of 8MHz.

Why STM32CubeMX Clock configuration tool is not allowed to set frequency more than 84MHz?

Please help to solve this issue.

Thanks,

Nandish Jasani.
