The reset input defines the signal to synchronous reset the CRC.That is correct.
"Asynchronous input signal reset is added" is there for earlier version 2.0 .
OK. Thanks for the info.
I did some experimentation. To get it to reset, I had to hold BOTH Enable AND Reset high long enough for a clock to occur (actually, I held them high for a couple of clock cycles). So, it appears that the Reset is synchronous. I wasn't clear (to me, at least) from the data sheet that Enable had to be high in order for reset to work. Perhaps some clarification in the next revision of the data sheet might be in order. Anyway, it's working now.
