1. STM32U5 enters the sleep mode, power consumption is 15ma/3.3V, and the working frequency is 160Mhz. Enter stop0 mode power consumption 3ma/3.3V, working frequency 160Mhz. The difference with the manual is quite large, I do not know why? (Other components on the PCB are in a power off state). 2 How to realize serial port wake-up and complete data reception in stop0 mode? Thank you for your guidance.
