beCAN CONTROLLER (Cont’d)
10.9.4.2 Reception Handling
For the reception of CAN messages, three
mailboxes organized as a FIFO are provided. In
order to save CPU load, simplify the software and
guarantee data consistency, the FIFO is managed
completely by hardware. The application accesses
the messages stored in the FIFO through the FIFO
output mailbox.

A received message is considered as valid when it
has been received correctly according to the CAN
protocol (no error until the last but one bit of the
EOF field) and It passed through the identifier fil-
tering successfully, see
Filtering.
