Universal Synchronous Asynchronous Receiver Transmitter (USART)

20.1

Flow Control with DMA

The RTS signal is not connected to the DMA. Therefore, when DMA is used, Flow Control is not

supported.

Workaround

None.

20.2

Bad Frame Detection

If a bad frame is received (i.e., incorrect baud rate) with the last data bit being sampled at 1, frame error

detection does not occur.

Workaround

There is no general workaround. When performing baud rate detection with receive part, the transmit

frame must be sent with a parity bit set to '0'.
