Figure 19-5. Manchester Frame error detection
Note:
When a Manchester framing error is detected the FEM bit and RxC bit are set at the same time.
This allows the application to execute the reception complete interrupt subroute when this error
conditon is detected.
When a Manchester framing error is detected, the EUSART receiver immediately enters in a
new start bit detection phase. Thus when a Manchester framing error is detected within a frame,
the receiver will process the rest of the frame as a new incomming frame and generate other
FEM errors.
