Bit 7: Reserved. This bit always reads 0 and must be set to 0.
Bits 6 4 (RXCS2 RXCS0: Receive Clock Source): Specify the receive clock source.
Bits 3 0 (RXBR3 RXBR0: Receiver Baud Rate): Used in conjunction with the time constant
register (TMC) to specify the baud rate of the baud rate generator in the receiver. For details, see
section 5.6, Baud Rate Generator.

Asynchronous/Byte synchronous/Bit synchronous mode
RXCS2 RXCS0 = 0, 0, 0:
suppressor does not function for the receive clock and receive data.
RXCS2 RXCS0 = 0, 1, 0:
suppressor of the ADPLL functions for the receive clock and receive data.
RXCS2 RXCS0 = 1, 0, 0:
is output from the RXC line.
RXCS2 RXCS0 = 1, 1, 0:
clock, which is output from the RXC line. The BRG output serves as the ADPLL operating
clock, and the noise suppressor functions for the receive data.
RXCS2 RXCS0 = 1, 1, 1:
clock. The RXC line input serves as the ADPLL operating clock, and the noise suppressor
functions for the receive data.
