Note that the values of the different PCAN-Status definitions are able to be bitwise combined. In some cases it is possible to get more than one error code as result of calling a function. 

*Note that the values of PCAN_ERROR_INITIALIZE and PCAN_ERROR_ILLOPERATION were changed! 

PCAN_ERROR_INITIALIZE changed from 0x40000 to 0x4000000 

PCAN_ERROR_ILLOPERATION changed from 0x80000 to 0x8000000
