FULLCAN MODE

When fullCAN mode is enabled, the Acceptance Filter itself takes care of receiving and storing messages for selected Standard
ID values on selected CAN buses, in the style of "FullCAN" controllers.
In order to set this bit and use this mode, two other conditions must be met with respect to the contents of Acceptance Filter RAM
and the pointers into it:
