The first time you call Crc16CalcBlock, pass zero.
If you need to call it multiple times (because you want to CRC more
than 64K of data, or because you want to do other processing during a
long computation), then you can call it repeatedly, passing in the
return value from the previous call (assuming you set bufP += count
before calling again).
Hope this helps,
