      Product Specification
      R
      SGCK1 -
      SGCK4
      (Spartan)
      Weak
      Pull-up
      (except
      SGCK4
      is DOUT)
      I or I/O
      Four Secondary Global inputs each drive a dedicated internal global net with short
      delay and minimal skew. These internal global nets can also be driven from
      internal logic. If not used to drive a global net, any of these pins is a
      user-programmable I/O pin.
      The SGCK1-SGCK4 pins provide the shortest path to the four Secondary Global
      Buffers. Any input pad symbol connected directly to the input of a BUFGS symbol
      is automatically placed on one of these pins.
      GCK1 -
      GCK8
      (Spartan-XL)
      Weak
      Pull-up
      (except
      GCK6 is
      DOUT)
      I or I/O
      Eight Global inputs each drive a dedicated internal global net with short delay and
      minimal skew. These internal global nets can also be driven from internal logic. If
      not used to drive a global net, any of these pins is a user-programmable I/O pin.
      The GCK1-GCK8 pins provide the shortest path to the eight Global Low-Skew
      Buffers. Any input pad symbol connected directly to the input of a BUFGLS symbol
      is automatically placed on one of these pins.
      CS1
      (Spartan-XL)
      I
      I/O
      During Express configuration, CS1 is used as a serial-enable signal for
      daisy-chaining.
      D0-D7
      (Spartan-XL)
      I
      I/O
      During Express configuration, these eight input pins receive configuration data.
      After configuration, they are user-programmable I/O pins.
      DIN
      I
      I/O
      During Slave Serial or Master Serial configuration, DIN is the serial configuration
      data input receiving data on the rising edge of CCLK. After configuration, DIN is a
      user-programmable I/O pin.
      DOUT
      O
      I/O
      During Slave Serial or Master Serial configuration, DOUT is the serial
      configuration data output that can drive the DIN of daisy-chained slave FPGAs.
      DOUT data changes on the falling edge of CCLK, one-and-a-half CCLK periods
      after it was received at the DIN input.
      In Spartan-XL Express mode, DOUT is the status output that can drive the CS1 of
      daisy-chained FPGAs, to enable and disable downstream devices.
      After configuration, DOUT is a user-programmable I/O pin.
      Unrestricted User-Programmable I/O Pins
      I/O
      Weak
      Pull-up
      I/O
      These pins can be configured to be input and/or output after configuration is
      completed. Before configuration is completed, these pins have an internal
      high-value pull-up resistor network that defines the logic level as High.
