35.11 Flow Control

This section does not apply to the LIN, DALI, or DMX modes.

Flow control is the means by which a sending UART data stream can be suspended by a receiving UART. Flow control prevents input buffers from overflowing without software intervention. The UART supports both hardware and XON/XOFF methods of flow control.

The flow control method is selected with the FLO bits. Flow control is disabled when both bits are cleared.
