      Pin Descriptions
      There are three types of pins in the Spartan/XL devices:
      Permanently dedicated pins
      User I/O pins that can have special functions
      Unrestricted user-programmable I/O pins.
      Before and during configuration, all outputs not used for the
      configuration process are 3-stated with the I/O pull-up resis-
      tor network activated. After configuration, if an IOB is
      unused it is configured as an input with the I/O pull-up resis-
      tor network remaining activated.
      Any user I/O can be configured to drive the Global
      Set/Reset net GSR or the global three-state net GTS. See
      tion.
      Device pins for Spartan/XL devices are described in

      Pin Description
      Permanently Dedicated Pins
      VCC
      X
      Eight or more (depending on package) connections to the nominal +5V supply
      voltage (+3.3V for Spartan-XL devices). All must be connected, and each must be
      decoupled with a 0.01 –0.1
      F capacitor to Ground.
      GND
      X
      Eight or more (depending on package type) connections to Ground. All must be
      connected.
      CCLK
      I or O
      I
      During configuration, Configuration Clock (CCLK) is an output in Master mode and
      is an input in Slave mode. After configuration, CCLK has a weak pull-up resistor
      and can be selected as the Readback Clock. There is no CCLK High or Low time
      restriction on Spartan/XL devices, except during Readback. See Violating the
      for an explanation of this exception.
      DONE
      I/O
      O
      DONE is a bidirectional signal with an optional internal pull-up resistor. As an
      open-drain output, it indicates the completion of the configuration process. As an
      input, a Low level on DONE can be configured to delay the global logic initialization
      and the enabling of outputs.
      The optional pull-up resistor is selected as an option in the program that creates
      the configuration bitstream. The resistor is included by default.
      PROGRAM
      I
      PROGRAM is an active Low input that forces the FPGA to clear its configuration
      memory. It is used to initiate a configuration cycle. When PROGRAM goes High,
      the FPGA finishes the current clear cycle and executes another complete clear
      cycle, before it goes into a WAIT state and releases INIT.
      The PROGRAM pin has a permanent weak pull-up, so it need not be externally
      pulled up to VCC.
      MODE
      (Spartan)
      M0, M1
      (Spartan-XL)
      I
      X
      The Mode input(s) are sampled after INIT goes High to determine the
      configuration mode to be used.
      During configuration, these pins have a weak pull-up resistor. For the most popular
      configuration mode, Slave Serial, the mode pins can be left unconnected. For
      Master Serial mode, connect the Mode/M0 pin directly to system ground.
