6-8

Baudrate inaccuracy

Divisor = 921600/Target Baud Rate. (Only Integer part)

ENUM = 8 * (921600/Targer - Divisor) ( Round up or down)

Inaccuracy = (Target Baud Rate – 921600/(Divisor + (ENUM/8))) * 100%

E.g.,

To calculate 500000 bps

Divisor = 1, ENUM = 7,

Inaccuracy = 1.7%

*The Inaccuracy should less than 2% for work reliably.

Special Note

1. If the target baudrate is not a special baudrate (e.g. 50, 75, 110, 134, 150, 200, 300, 600, 1200,

1800, 2400, 4800, 9600, 19200, 38400, 57600, 115200, 230400, 460800, 921600), the termios

cflag will be set to the same flag.

2. If you use stty to get the serial information, you will get speed equal to 0.
