What clocking modes do Sealevel synchronous serial adapters support?

Sealevel synchronous serial adapters support the three most common non-encoded clocking modes:

1. The Sealevel serial adapter provides the clock using the baud rate generator (BRG) that will be used by the other serial device for transmitting and receiving.
2. The other device provides an external clock that the Sealevel serial adapter will use for transmitting and receiving.
3. The Sealevel serial adapter provides the clock (using the BRG) for the transmitted data and the other device provides an external clock for its transmitted data. The benefit of this mode is the transmit and receive data rates do not have to match.
