I try to understand CAN filtering mechanism to use it in my application. I understand that it is possible to filtering by ID type, frame type and ID scale.
In the case of standard ID, I understand that it's possible to filtering on all bits off the ID. But for the extended ID, I only see EXID[17:0] (32 bits filter) and EXID[17:15] (16 bits filter).
It means it is impossible to filtering on the MSB bits of the extended ID (EXID[28:18]) ? Or this MSB is on STID[10:0] in the case of extended ID ?
