Start
A received frame is triggered by a start event and can be followed by synchronization data
before data transmission.
The start event is configured by writing to the RCMR register. See
The frame synchronization is configured by writing to the Receive Frame Mode Register
(RFMR). See
The receiver uses a shift register clocked by the receiver clock signal and the start mode
selected in the RCMR register. The data is transferred from the shift register depending on the
data format selected.
When the receiver shift register is full, the SSC transfers this data in the Receive Holding Regis-
ter (RHR), the Receive Ready bit is set in the SR register (SR.RXREADY) and the data can be
read in the RHR register. If another transfer occurs before a read of the RHR
Receive Overrun bit is set in the SR register (SR.OVRUN) and the receiver shift register is trans-
ferred to the RHR register.
