Bit 6: QRSS Enable (QRSS).
When 0, the pattern generator configuration is controlled by PTS, PLF[4:0], and
PTF[4:0], and BSP[31:0]. When 1, the pattern generator configuration is forced to a PRBS pattern with a
generating polynomial of x

+ x

+ 1. The output of the pattern generator is forced to one if the next 14 output bits
are all 0.

Bit 5: Pattern Type Select (PTS).
When 0, the pattern is a PRBS pattern. When 1, the pattern is a repetitive
pattern.
Bits 4 to 0: Pattern Length Feedback (PLF[4:0]).
These bits control the “l(fā)ength” feedback of the pattern
generator. The length feedback is from bit n of the pattern generator (n = PLF[4:0] +1). For a PRBS signal, the
feedback is an XOR of bit n and bit y. For a repetitive pattern the feedback is bit n.

Bits 4 to 0: Pattern Tap Feedback (PTF[4:0]).
These bits control the PRBS “tap” feedback of the pattern
generator. The tap feedback is from bit y of the pattern generator (y = PTF[4:0] +1). These bits are ignored when
programmed for a repetitive pattern. For a PRBS signal, the feedback is an XOR of bit n and bit y.
