EC4-200 specific functions
EC_Util.lib library
This library contains the functions shown in the illustration below:
CAN_BUSLOAD function

and bus load to the transferred addresses.
If the bus load calculation is not yet completed or the CAN
controller has not yet been initialised, the function returns FALSE.
Information on evaluating the return value is provided in the
browser command „canload“ on page 60.
