Bits 7:0 – UBBRm[7:0]: USARTm Baud Rate Register
This is a 12-bit register which contains the USARTm baud rate. The UBRRmH contains the four most
significant bits, and the UBRRmL contains the eight least significant bits of the USARTm baud rate.
Ongoing transmissions by the transmitter and receiver will be corrupted if the baud rate is changed.
Writing UBRRmL will trigger an immediate update of the baud rate prescaler.
