Description
Hello, i have loaded successfully last version, i have replaced CRC table with calculation. I have encountered errors on UART reception. 115200baud speed. Transmittion from atsam->atmega works great(perfect timing and levels), also atmega->atsam works (checked by external receiver, perfect timing and levels), but atsam passes invalid data to serial terminal in PC. Basically i am sending "POS 1|1|1|1\r\n" and i get "POScddd>d" in terminal or "Pdcdddkd".. Does anybody encountered something similar?

Research direction
Start by reproducing the UART reception problem described for ArduinoCore-megaavr version 1.8.8 at 115200 baud, using the reported "POS 1|1|1|1\r\n" transmission. Compare the ATmega4809's received data with the external receiver output and inspect the UART reception path. Done means identifying and correcting the cause of the corrupted terminal output.
