Hey,
I´m working on implementing all 3 CAN bus interfaces on a F767ZI.
Looking through the Reference Manual it states that dual CAN set ups feature 28 filter banks and single CAN set ups feature 14 filter banks. However looking at Table 280 it states that CAN1 and 2 share 26 filter banks and CAN3 has 14.
Is the 26 a typo or is the number actually limited on this MCU?

Hi @AndreM ,
I confirm that, the bxCAN have 28 filter banks shared between CAN1 and CAN2 for dual CAN.
The 26 filter mentioned in table 280 is a typo and will be corrected in the coming release.
