CAN ports
DIDO provides two DCAN interfaces (DCAN0 and DCAN1) for
supporting distributed realtime control with a high level of
security. The DCAN interfaces implement the CAN protocol
version 2.0 part A, B and supports bit rates up to 1 Mbit/s.
7.6.1
DCAN0
DCAN0 port is connected to on-board transceiver which
converts the single-ended CAN signals of the controller to the
differential signals of the physical layer.
