I am working with the EMAC on the MC9S12NE64 16 bit processor and am trying to define a multicast filter via the MCHASH registers. All the documentation I have found says to use th 32-bit CRC generator and selecting the 6 most significant bits ...
The problem is that I can find MANY 32-bit CRC calculations on the web. Can anyone help me find the correct CRC calcuation?
A little background: I am communicating (successfully) via the network using broadcast messages and multicast messages. I would like to filter all but a couple multicast groups out.
Thanks in advance!
