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. RDWR_B (or WRITE) must be either driven Low or pulled down exernally. One option is shown.
4. The BUSY pin is only available with the XCFxxP Platform Flash PROM, and the connection is only required for high
5. In Slave SelectMAP mode, the configuration interface can be clocked by an external oscillator, or optionally the
6 For the XCFxxP the CF pin is a bidirectional pin. For the XCFxxP, if CF is not connected to PROGB, then it must be

CLKOUT signal can be used to drive the FPGA's configuration clock (CCLK). If the XCFxxP PROM's CLKOUT signal is
used, then it must be tied to a 4.7KΩ resistor pulled up to V
