Yes it is directly configurable, and it is more than ONE time configurable.

Disadvantage of not using PROM is that you need to reflash the core every time 
you remove the power. If you flash a PROM this will also be there after removing 
the power supply (PROM can also be flashed many times). The next time you 
connect the power you can automatically "boot/load the core" to the FPGA from 
the PROM.
