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 pin, and
the receiver block can generate an external clock on the RX_CLOCK pin.
This allows the SSC to support many Master and Slave Mode data transfers.
Interrupt Control
• an external clock received on the TX_CLOCK pin
• the receiver clock
• the internal clock divider
• an external clock received on the RX_CLOCK pin
• the transmitter clock
• the internal clock divider
