pseudo-random pattern generation (PRPG)
A pseudo-random pattern is generated in the shift-register elements of the selected BSCs on each rising edge
of TCK, updated in the shadow latches, and applied to the associated device output-mode I/O pins on each
falling edge of TCK. Figures 5 and 6 illustrate the 36-bit linear-feedback shift-register algorithms through which
the patterns are generated. An initial seed value should be scanned into the BSR before performing this
operation. A seed value of all zeroes does not produce additional patterns.
