51.3.1 UART Baud Rate Registers:High (UARTx_BDH)
This register, along with the BDL register, controls the prescale divisor for UART baud
rate generation. To update the 13-bit baud rate setting (SBR[12:0]), first write to BDH to
buffer the high half of the new value and then write to BDL. The working value in BDH
does not change until BDL is written.
BDL is reset to a non-zero value, but after reset the baud rate generator remains disabled
until the first time the receiver or transmitter is enabled (C2[RE] or C2[TE] bits are set).
