SerialParams - this parameter sets the serial mode options for parity and stop bits:
Setting Mode
0x00
No parity, 8 data bits, 1 stop bit (default)
0x01
No parity, 8 data bits, 2 stop bits
0x02
Reserved
0x03
Reserved
0x04
Even parity, 8 data bits, 1 stop bit
0x05
Even parity, 8 data bits, 2 stop bits
0x06
Odd parity, 8 data bits, 1 stop bit
0x07
Odd parity, 8 data bits, 2 stop bits
Note that 8-bit data with no parity is capable of carrying 7-bit data with parity for compatibility without loss
of generality for legacy applications that may require it.
