Bit 6: QRSS Enable (QRSS)
When 0, the pattern generator configuration is controlled by PTS, PLF[0:4], and
PTF[0:4], and BSP[0:31]. When 1, the pattern generator configuration is forced to a QRSS pattern with a
generating polynomial of x
+ x
+ 1. The output of the pattern generator is forced to one if the next fourteen
output bits are all zero.
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 Tap Feedback (PTF[4:0])
These five 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. The values
possible are outlined in Section
8.15
.
