Description
7:5
PQT[2:0]
000
R/W
Preamble quality estimator threshold. The preamble quality estimator
increases an internal counter by one each time a bit is received that is
different from the previous bit, and decreases the counter by 8 each
time a bit is received that is the same as the last bit.
A threshold of 4·PQTfor this counter is used to gate sync word
detection. When PQT=0a sync word is always accepted
