Using C5510 HPI as GPIO

It has been awhile since I have used the C55 family and I can't
remember if they support using the HPI as GPIO if you are not using the
HPI.  I seem to recall that some of the TI DSPs can do that, but I
don't see anything in the docs that says the C5510 is capable of it.

Anyone know for sure if the C5510 HPI can be used as GPIO?
