How does one define the filter for a CAN A message, when the ID is only 11 bits?
If using 16-bit filter, what should be put to the EXTID[17:15]?

Whatever you have on the wire, it is a one-to-one deal, not magic. If it's random crap you're going to need to mask it...

Match = (ID << 5)
Mask = 0x7FF << 5;
Let me go find the diagram, I've posted it a bunch of times to older iteration of the forum...

For the identifier list expect you're going to have to exactly match the bit patterns you've enumerated.

Just that CAN A does not have EXTID. CAN A ID is only 11 bits.
What do the EXTID-bits match to?
Or maybe one needs to use masking with CAN A?

As I thought. Thanks for confirmation.
