[6] Determine whether or not to use the Infrared mode.
0 = Normal mode operation
1 = Infrared Tx/Rx mode
[5:3] Specify the type of parity generation and checking during UART
transmit and receive operation.
0xx = No parity
100 = Odd parity
101 = Even parity
110 = Parity forced/checked as 1
111 = Parity forced/checked as 0
[2] Specify how many stop bits are to be used for end-of-frame
signal.
0 = One stop bit per frame
1 = Two stop bit per frame
[1:0] Indicate the number of data bits to be transmitted or received per
frame.
00 = 5-bits
10 = 7-bits
