Start = Low Level on TF
Start = Falling Edge on TF
Start = Low Level on RF
Start = Falling Edge on RF
Start = High Level on TF
Start = Rising Edge on TF
Start = Level Change on TF
Start = Any Edge on TF
Start = High Level on RF
Start = Rising Edge on RF
Start = Level Change on RF
Start = Any Edge on RF
A start can be programmed in the same manner on either side of the Transmit/Receive Clock
Register (RCMR/TCMR). Thus, the start could be on TF (Transmit) or RF (Receive).
Moreover, the Receiver can start when data is detected in the bit stream with the Compare
Functions.
Detection on TF/RF input/output is done by the field FSOS of the Transmit/Receive Frame Mode
Register (TFMR/RFMR).
