      Setting CCLK Frequency
      For Master modes, CCLK can be generated in either of two
      frequencies. In the default slow mode, the frequency
      ranges from 0.5 MHz to 1.25 MHz for XC4000E and
      XC4000EX devices and from 0.6 MHz to 1.8 MHz for
      XC4000XL devices. In fast CCLK mode, the frequency
      ranges from 4 MHz to 10 MHz for XC4000E/EX devices and
      from 5 MHz to 15 MHz for XC4000XL devices. The fre-
      quency is selected by an option when running the bitstream
      generation software. If an XC4000 Series Master is driving
      an XC3000- or XC2000-family slave, slow CCLK mode
      must be used. In addition, an XC4000XL device driving a
      XC4000E or XC4000EX should use slow mode. Slow mode
      is the default.
      Table 19: XC4000 Series Data Stream Formats
      Data Stream Format
      The data stream (“bitstream”) format is identical for all con-
      guration modes.
      The data stream formats are shown in Table 19. Bit-serial
      data is read from left to right, and byte-parallel data is effec-
      tively assembled from this serial bitstream, with the rst bit
      in each byte assigned to D0.
      The conguration data stream begins with a string of eight
      ones, a preamble code, followed by a 24-bit length count
      and a separator eld of ones. This header is followed by the
      actual conguration data in frames. The length and number
      of frames depends on the device type (see Table 20 and
      Table 21). Each frame begins with a start eld and ends
      with an error check. A postamble code is required to signal
      the end of data for a single device. In all cases, additional
      start-up bytes of data are required to provide four clocks for
      the startup sequence at the end of conguration. Long
      daisy chains require additional startup bytes to shift the last
      data through the chain. All startup bytes are don’t-cares;
      these bytes are not included in bitstreams created by the
      Xilinx software.
      A selection of CRC or non-CRC error checking is allowed
      by the bitstream generation software. The non-CRC error
      checking tests for a designated end-of-frame eld for each
      frame. For CRC error checking, the software calculates a
      running CRC and inserts a unique four-bit partial check at
      the end of each frame. The 11-bit CRC check of the last
      frame of an FPGA includes the last seven data bits.
      Detection of an error results in the suspension of data load-
      ing and the pulling down of the INIT pin. In Master modes,
      CCLK and address signals continue to operate externally.
      The user must detect INIT and initialize a new conguration
      by pulsing the PROGRAM pin Low or cycling Vcc.
