The transmitter clock can be generated by:
The receiver clock can be generated by:
Furthermore, the transmitter block can generate an external clock on the TX_CLOCK I/O pad,
and the receiver block can generate an external clock on the RX_CLOCK I/O pad.
This allows the SSC to support many Master and Slave Mode data transfers.
