6-3 Communication Protocol
Serial data transmission is an asynchronous serial data transmission: 1 frame =
11 bits (3 types of format shown in below figures)
 8,N,2: 1 start bit，8 data bits，2 stop bits
START BIT 0 BIT 1 BIT 2 BIT 3 BIT 4 BIT 5 BIT 6 BIT 7 STOP STOP
 8,E,1: 1 start bit，8 data bits，1 even parity bit，1 stop bit
START BIT 0 BIT 1 BIT 2 BIT 3 BIT 4 BIT 5 BIT 6 BIT 7
EVEN
PARITY
STOP
 8,O,1: 1 start bit，8 data bits，1 odd parity bit，1 stop bit
START BIT 0 BIT 1 BIT 2 BIT 3 BIT 4 BIT 5 BIT 6 BIT 7
