The transmitter and receiver can both be programmed to start their operations when an event
occurs, respectively in the Transmit Start Selection (START) field of SSC_TCMR and in the
Receive Start Selection (START) field of SSC_RCMR.
Under the following conditions the start event is independently programmable:
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).
Detection on TF/RF input/output is done through the field FSOS of the Transmit / Receive
Frame Mode Register (TFMR/RFMR).
Generating a Frame Sync signal is not possible without generating it on its related output.
• Continuous. In this case, the transmission starts as soon as a word is written in SSC_THR
• Synchronously with the transmitter/receiver
• On detection of a falling/rising edge on TK/RK
• On detection of a low level/high level on TK/RK
• On detection of a level change or an edge on TK/RK
and the reception starts as soon as the Receiver is enabled.
