Manchester Framing error detection
Figure 19-4. Manchester Decoder operation
Note:
When configured in Manchester mode, the framing error (FE) of the USCRA register is not used,
the EUSART generates a dedicated Frame Error Manchester (FEM) when a data data bit is not
detected during the detection window (See
