STM32L071 MCU LPUART use LSE to configure BaudRate 9600. Actual BaudRate is 8300 or 11000.Error islarge. LSE is 32.768kHz ,One cycle is 30.517 us。One cycle of BaudRate 9600 is 3.4 times of LSE。But LSE frequency division can only be an integral multiple。
So,LPUART can not use LSE to configure BaudRate 9600?
