PLR: PATTERN LENGTH REGISTER (ADDRESS=04 HEX)
5. 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.
PTR: POLYNOMIAL TAP REGISTER (ADDRESS=05 HEX)
6. PATTERN CONTROL REGISTER
The Pattern Control Register (PCR) is used to configure the operating parameters of the DS21372 and to
control the patterns being generated and received. Also the PCR is used to control the pattern
synchronizer and the error and bit counters.
