• Bit 15:0 – MUBRR15:0: Manchester Receiver Baud Rate Register

This is a 16-bit register which contains the maximum value for the Machester receiver counter.

The MUBRRH contains the eight most significant bits, and the MUBRRL contains the eight least

significant bits. Ongoing transmissions by the Receiver will be corrupted if the baud rate is

changed.
