CAN Controller
Atmel ATmega16/32/64/M1/C1
Error Signalling
If one or more errors are discovered by at least one node using the above mechanisms, the
current transmission is aborted by sending an "error flag". This prevents other nodes accept-
ing the message and thus ensures the consistency of data throughout the network. After
transmission of an erroneous message that has been aborted, the sender automatically
re-attempts transmission.
The CAN controller implemented into ATmega16/32/64/M1/C1 offers V2.0B Active.
This full-CAN controller provides the whole hardware for convenient acceptance filtering and
message management. For each message to be transmitted or received this module contains
one so called message object in which all information regarding the message (e.g. identifier,
data bytes etc.) are stored.
During the initialization of the peripheral, the application defines which messages are to be
sent and which are to be received. Only if the CAN controller receives a message whose iden-
tifier matches with one of the identifiers of the programmed (receive-) message objects the
message is stored and the application is informed by interrupt. Another advantage is that
incoming remote frames can be answered automatically by the full-CAN controller with the
corresponding data frame. In this way, the CPU load is strongly reduced compared to a
basic-CAN solution.
Using full-CAN controller, high baudrates and high bus loads with many messages can be
handled.
