Hi,

if you want to receive more IDs then you can have several options.

- configure more MBs, one MB for each ID to be received

- you can use masking registers to allow receive all IDs or range of IDs into single or several MBs

- configure RXFIFO and set ID filter table with a IDs to be received.

BR, Petr
