        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

        F capacitor to Ground.
        Eight or more (depending on package type) connections to Ground. All must be con-
        nected.
        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 Maximum High and
        Low Time Specification for the Readback Clock
        on page 32
        for an explanation of this
        exception.
        DONE is a bidirectional signal with an optional internal pull-up resistor. As an 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 con-
        figuration bitstream. The resistor is included by default.
        PROGRAM is an active Low input that forces the FPGA to clear its configuration mem-
        ory. 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.
        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 con-
        figuration mode, Slave Serial, the mode pins can be left unconnected. For Master Serial
        mode, connect the Mode/M0 pin directly to system ground.
        PWRDWN is an active Low input that forces the FPGA into the Power Down state and
        reduces power consumption. When PWRDWN is Low, the FPGA disables all I/O and
        initializes all flip-flops. All inputs are interpreted as Low independent of their actual level.
        VCC must be maintained, and the configuration data is maintained. PWRDWN halts
        configuration if asserted before or during configuration, and re-starts configuration when
        removed. When PWRDWN returns High, the FPGA becomes operational by first en-
        abling the inputs and flip-flops and then enabling the outputs. PWRDWN has a default
        internal pull-up resistor.
        User I/O Pins That Can Have Special Functions
        If boundary scan is used, this pin is the Test Data Output. If boundary scan is not used,
        this pin is a 3-state output without a register, after configuration is completed.
        To use this pin, place the library component TDO instead of the usual pad symbol. An
        output buffer must still be used.
