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 TK I/O pad, and the
receiver block can generate an external clock on the RK I/O pad.
This allows the SSC to support many Master and Slave-mode data transfers.
