External bus interface

For the bi-directional signals, I've selected them as inout as the direction and data as the type, since they will be transferring data.

Here are the error messages.

When set as Avalon Master, clock type is flush(?), bidir is data:

ERROR:
slave avalonM is not mastered by anyone
Error in processing.  System NOT successfully generated.

When set as Avalon Register Slave, clock type is irq, bidir is data:

ERROR:
name (e_signal=HASH(0x36f8614)) is no good for a signal
Error in processing.  System NOT successfully generated.

When set as Avalon Memory Slave, clock type is irq, bidir is data:
