XMC4800: How to use both Ethercat + EBU

Hello,

we are evaluating XMC4800 for an ETHERCAT solution.
Beside ETHERCAT we need external bus Interface (EBU) for accessing FPGA.
16 Bit Adress/Data multiplexed

According to the Port I/O function table ( Datasheet 2.2.2.1)we have not found a valid solution for the pin assignment.

We have conflicts with PINs P0.4, P0.5 and P0.6
They are used for both EBU and ECAT and do not have any alternative mapping.

Any solution or is it impossible at all to use XMC4800 with ECAT and EBU ?

Many Thanks
