24.5.10 Baud Register
The USART.BAUDL and USART.BAUDH register pair represents the 16-bit value, USART.BAUD. The low byte [7:0] (suffix L) is accessible at the original offset. The high byte [15:8] (suffix H) can be accessed at offset + 0x01. For more details on reading and writing 16-bit registers, refer to 8.5.6 Accessing 16-bit Registers.
Ongoing transmissions of the Transmitter and Receiver will be corrupted if the baud rate is changed. Writing this register will trigger an immediate update of the baud rate prescaler. For more information of how to set the baud rate, see Table 24-2
