22.5.10 Baud Register
Name: BAUD
Offset: 0x08
Reset: 0x00
Property: -
The USARTn.BAUDL and USARTn.BAUDH register pair represents the 16-bit value, USARTn.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.
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 on
how to set the baud rate, see
