            Description

            Serial DPM examples calling SerialDPM_Init() to set 'read' and 'write' function pointers in the device instance structure, if CIFX_TOOLKIT_HWIF is defined.

            The following function cifXTkHWFunctions_InitializeDataStructures() resets this device instance by using a memset.
            This memset sets already initialized pointers back to 0x0, resulting in a programm access viloation.

            This can be prevented if the order of the two calls is exchanged.
