Synchronous Rates

The serial synchronous ports operate at any rate from 50 Kbaud to 256 Kbaud when the clock is generated from the serial port controller. When the clock is generated from an external source, the synchronous ports operate at up to 384 Kbaud. Clock generation is accurate within 1 percent for any rate that is generated between 50 Kbaud and 256 Kbaud.
