17.4.7 CANopen configuration

The CAN API supports an Object Dictionary interface and the SDO protocol. In order to
activate it, the CANopen configuration function has to be called with a pointer to a
structure with the CANopen Node ID (1...127), the message object numbers to use for
receive and transmit SDOs, a flag to decide whether the CANopen SDO handling should
happen in the interrupt serving function automatically or via the dedicated API function,
and two pointers to Object Dictionary configuration tables and their sizes. One table
contains all read-only, constant entries of four bytes or less. The second table contains all
variable and writable entries as well as SDO segmented entries.
