XC3000 Series Field Programmable Gate Arrays
A re-program is initiated.when a configured XC3000 series
device senses a High-to-Low transition and subsequent >6
pin is externally held permanently Low, a High-to-Low tran-
sition and subsequent >6 s Low time on the RESET pack-
age pin.
The device returns to the Clear state where the configura-
tion memory is cleared and mode lines re-sampled, as for
an aborted configuration. The complete configuration pro-
gram is cleared and loaded during each configuration pro-
gram cycle.
Length count control allows a system of multiple Field Pro-
grammable Gate Arrays, of assorted sizes, to begin opera-
tion in a synchronized fashion. The configuration program

frames generated by the Development System.
The Length Count produced by the program = [(40-bit preamble + sum of program data + 1 per daisy chain device)

reached.

generated by the development system begins with a pre-
amble of 111111110010 followed by a 24-bit length count
representing the total number of configuration clocks
needed to complete loading of the configuration pro-
gram(s). The data framing is shown in
FPGAs connected in series read and shift preamble and
length count in on positive and out on negative configura-
tion clock edges. A device which has received the pream-
ble and length count then presents a High Data Out until it
has intercepted the appropriate number of data frames.
When the configuration program memory of an FPGA is full
and the length count does not yet compare, the device
shifts any additional data through, as it did for preamble
and length count. When the FPGA configuration memory is
full and the length count compares, the device will execute
