5.0 POLYNOMIAL TAP REGISTER
Polynomial Tap Bits PT4 - PT0 determine the feedback position of Tap B connected to the XOR input of
the pattern generator. Feedback Tap B provides one of two feedback paths within the pattern generator.
Please refer to Figure 2 for a block diagram of the pattern generator and to Tables 4 and 5 for register
programming examples.
