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 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 1

Bits 15:8 – BAUD[15:8]: USART Baud Rate high byte

USART Baud Rate high byte

These bits hold the MSB of the 16-bit Baud register.

Bits 7:0 – BAUD[7:0]: USART Baud Rate low byte

USART Baud Rate low byte

These bits hold the LSB of the 16-bit Baud register.
