Hi,

I found out by experimenting, that the hardware address filter of the Atmega128RFR2 will pass ALL frames if the "destination addressing mode" bits of the incoming frame are set to "reserved" (01). The strange part in this behavior is that this way also frames with bad CRC are passed through!

Is this intentional? I cannot find any information about this behavior from the datasheet?

How are you verifying that those frames are with wrong CRC?

I double checked and guess what -- the crc in my almost random frame was accidentally correct! So, everything working as expected, nothing to see here folks... :)
