register bit LCR1.EPRM is set. No pattern is also detected if signal
“alarm simulation” is active. Detection of all_zero or all_ones is
done over 12, 16, 21 or 24 consecutive bits, dependent on the
choosed PRBS polynomial (11, 15, 20 or 23). Because every bit
error in the PRBS increments the bit error counter BEC, no special
status information like “PRBS detected with errors” is given here
no pattern detected.
