For Mode pin connections and DONE pin pullup value, refer to the appropriate FPGA data sheet.
For compatible voltages, refer to the appropriate data sheet.
CS_B (or CS) and RDWR_B (or WRITE) must be either driven Low or pulled down exernally. One option is shown.
The BUSY pin is only available with the XCFxxP Platform Flash PROM, and the connection is only required for
high-frequency SelectMAP mode configuration. For BUSY pin requirements, refer to the appropriate FPGA data sheet.
For the XCFxxP the CF pin is a bidirectional pin.
