Tab.3/7: Pin assignment of the CAN interface (bus)
The device does not feed any supply current into the CPstring,
and it also does not take any supply current from the CPstring.
The functional principle of the CAN interface depends on the
system parameters set for the device. To use the CAN interface,
it must be configured appropriately. The protocol to be used
is also defined here (see sections 4.9.4 and 4.9.5).
