User manual
12.2 Acceptance filter Bypass mode
12.3 Acceptance filter Operating mode
12.4 FullCAN mode
The Acceptance Filter Bypass Mode can be used for example to change the acceptance
filter configuration during a running system, e.g. change of identifiers in the ID-Look-up
Table memory. During this re-configuration, software acceptance filtering has to be used.
It is recommended to use the ID ready Interrupt (ID Index) and the Receive Interrupt (RI).
In this mode all CAN message are accepted and stored in the Receive Buffers of active
CAN Controllers.
The Acceptance Filter is in Operating Mode when neither the AccOff nor the AccBP in the
Configuration Register is set and the eFCAN = 0.
The Acceptance Filter is in Operating Mode when neither the AccOff nor the AccBP in the
Configuration Register is set and the eFCAN = 1. More details on FullCAN mode are
available in
Four 12-bit section configuration registers (SFF_sa, SFF_GRP_sa, EFF_sa,
EFF_GRP_sa) are used to define the boundaries of the different identifier sections in the
ID-Look-up Table Memory. The fifth 12-bit section configuration register, the End of Table
address register (ENDofTable) is used to define the end of all identifier sections. The End
of Table address is also used to assign the start address of the section where FullCAN
Message Objects, if enabled are stored.
Table 442. Section configuration register settings
The Whole ID Look-up Table RAM is only word accessible. A write access is only possible
during the Acceptance Filter Off or Bypass Mode. Read access is allowed in all
Acceptance Filter Modes.
