Why, when transmitting at 115200 baud, after transmitting the Tx stop bit, the callback occurs after 8.5us? Does HAL add more delay? When using GPIO I measure the time on the scope from stop bit to stop bit I get 100us instead of 87us. Configuration ...

I'm using STM32G0B1 and UART works as 1-wire , 64MHz clock. I'm rising GPIO before Tx enable and clear this GPIO in TX callback, but after the last byte was transmitted. In scope check the GPIO I get ~8.5us between stop bit transmitted and Tx callba...

I have written a simple application that takes characters from one UART and relays them to another. main is empty. Only two callbacks of HAL Rx and Tx are used.
