NBSTOP: Number of Stop Bits
The interpretation of the number of stop bits depends on SYNC.
CHMODE: Channel Mode
MODE9: 9-bit Character Length
0 = CHRL defines character length.
1 = 9-bit character length.
CKLO: Clock Output Select
0 = The USART does not drive the SCK pin.
1 = The USART drives the SCK pin if USCLKS[1] is 0.

Mode Description
Normal Mode
The USART Channel operates as an Rx/Tx USART.
Automatic Echo
Receiver Data Input is connected to TXD pin.
Local Loopback
Transmitter Output Signal is connected to Receiver Input Signal.
Remote Loopback
RXD pin is internally connected to TXD pin.
