R/W
TX Test Pattern
Select
Selects between the square wave or
pseudo-random pattern generator. The
following encodings are defined:
• 1’b1: Square wave
• 1’b0: Pseudo-random pattern or
PRBS
[0]
R/W
Data Pattern Select
Selects the data pattern for the pseudo-
random pattern. The following
encodings are defined:
• 1’b1: Two Local Faults. Two, 32-bit
ordered sets are
XOR
d with the
pseudo-random pattern.
• 1’b0: All 0’s
