|
Select the data bits.
|
Parity
|
None/Even/Odd/Mark/Space
|
None
|
A parity bit can be sent with the data bits to detect some
transmission errors.
-
None: No parity bits are sent.
-
Even: Parity bit is 0 if the number of 1s in the data
bits is even.
-
Odd: Parity bit is 0 if the number of 1s in the data
bits is odd.

'start' signal can be sent to restart the flow. Hardware flow
control uses two wires to send start/stop signals.
