Hello All,Test to create a new topic 😉  Best RegardsImen 1 1        

Testing a board with STM32U5A5. VDD is 3.3VI have configured one GPIO as input with an external pullup to 3.3V through a 470k ohm resistor.The input reads high, but when I measure the input with a scope, I read 2.2V on the input, which is below 0.7VDD which is guaranteed as V_IH, but above 0.5VDD+0.2 which is specified by design as V_IH.Is 470k ohm too high of a pullup resistance?

Test signature

When using PLL3Q as input with a frequency of 32MHz for USBPHY I have a RCC_CCIPR1 register initialized at value 0x2a00 when entreing USB_CoreReset function that is not correct (should be 0x2b00).
