Notes
1. For Mode pin connections and DONE pin pull-up value, refer to the appropriate FPGA data sheet.
2. For compatible voltages, refer to the appropriate data sheet.
3. In Slave Serial mode, the configuration interface can be clocked by an external oscillator, or optionally the CLKOUT
4. For the XCFxxP the CF pin is a bidirectional pin.
