9-Bit Mode
Start Bit Flow Control
The serial interface is configured to transmit and receive a ninth data bit. This ninth bit is
used to transmit or receive a software generated parity bit. It is used as an address/data bit
in a multi-node system such as RS-485.
If flow control is needed, start bit flow control is used. Start bit flow control requires the
receiving device send the start bit. The transmitter waits for the start bit, then transmit its
data following the start bit.
