RATECHK 1 Data rate check
the data rate is automatically extracted from the HEADER field.
the data rate can be compared to RATE with a tolerance of plus or minus RATETOL.
Data rate is computed from a unit of 1.56
µ
s (Reference clock divided by 16).
0: data rate not checked.
1: data rate check done (header ignored if check fails).
