Can-bus Connector
The CAN controller performs communication in accordance with the BOSCH CAN Protocol Ver-
sion 2.0B Active1 (standard format and extended format). The bit rate can be programmed to
a maximum of 1Mbit/s. To connect the CAN controller module to the CAN bus, it is necessary
to add transceiver hardware.
When communicating in a CAN network, individual message objects are configured. The mes-
sage objects and the identifier masks for the receive filter for the received messages are
stored in the message RAM.
Controller Area Network (CAN or CAN-bus) is a message based protocol designed specifically
for automotive applications but now is also used in other areas such as industrial automation
and medical equipment.
