Runs the PCI config cycle on the AIM board on the A16 address specified in
in->ul_A16Addr, regardless of its protocoll and writes its data into the output
parameters px_PCI_Info1 and px_PCI_Info2. Using these output parameters an
AVI429 board or an AMC429 board on an AVC-2 carrier can be initialized using the
function AiVme429MapModule().

Is a User defined address in the VME A16 address space, where the board is mapped with
the boards DIP-switch. This address is the A16 address where the CPU accesses the A16
space in his local memory and can be different to the real physical A16 address (Typically
there is a qualifier in the upper half of the long word) . The size of the address space must
be 4 kByte.
