I have a custom board that I am getting ready to program that is using the STM32U575. I am a little confused about the clock configuration. My board has an external 32768 crystal. I am not sure I have the MX program clock configuration correct. I wan...

One more thing I noticed. I have used various M4 and M7 microcontrollers over the years. The peripheral clock is usually SysClk/2. The clocks going out to the UART, I2C,... are 160mhz. Does the M33 core allow the full sysclk speed, or should those cl...

The following is from the STM32U5 Users Manual. This seems to say that the clocks can be synchronized against the LSE. Am I misunderstanding what it states? Hardware auto calibration with LSE (PLL-mode)When a 32.768 kHz external oscillator ispresent ...
