Configuration Data
Configuration data to define the function and interconnection within an FPGA are loaded from an external storage
at powerup and on a reprogram signal. Several methods of automatic and controlled loading of the required data
are available. Logic levels applied to mode selection pins at the start of configuration time determine the method to
be used (see Table 2). The data may be either bit-serial or byte-parallel, depending on the configuration mode.
Various Lucent programmable gate arrays have different sizes and numbers of data frames. For the ATT3020, con-
figuration requires 14779 bits for each device, arranged in 197 data frames. An additional 40 bits are used in the
header (see Figure 20).
* The FPGA devices require four dummy bits minimum.
