RATECHK

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

µs (Reference clock divided by 16).

0: data rate not checked.

1: data rate check done (header ignored if check fails).

reset value: 0
