R7FA2L1A93CNE CAN react on all CAN ID

Question

Hi, 
 i have the need to monitor a lot a CAN IDs. Is this possible with the can Stack of the FSP Configuration. 
 I have the need to check the can message regardless which CAN Identifier is used. Therefore I can not assign a CAN ID to the mailboxes. 
 Thanks Michael

You can set a group mask to allow all CAN IDs:

If all bits are '1' then the mailbox can listen only to one ID (fully masked). 
 If all or some bits are '0' then the mailbox can listen to multiple IDs depending on the mask. 
 The above option sets the MKR registers:

Certainly the hardware supports this by opening up the acceptance filtering where the CAN-ID completely masked. 
 It would seem to me that if you don't need anything else from the FSP CAN stack, then you would be better off using your own simplified CAN stack since it isn't doing much of anything beyond pushing all msgs to a common handler.
