CS and WRITE must be either driven Low or pulled down externally. One option is shown.
For Mode pin connections and Done pullup value, refer to the appropriate FPGA data sheet.
External oscillator required for Virtex/Virtex-E SelectMAP or Virtex-II/Virtex-II Pro Slave-SelectMAP modes.
For compatible voltages, refer to the appropriate FPGA data sheet.
CS and WRITE must be pulled down to be used as I/O. One option is shown.
For Mode pin connections and Done pullup value and if Drive Done configuration option is not active, refer to
the appropriate FPGA data sheet.
