C6474 POR Clarifcation...

Can I assert PORn on the 6474 more than once on a board that’s already powered up?  When a board is first powered-up, I de-assert PORn, boot/load my code, and run.  At this point, can I re-assert PORn, then de-assert it again, reboot/reload my code, and run again? 

I seem to remember when working with the 6700 series DSP’s, that PORn could only be asserted/de-asserted once.  After that, a full power-cycle of the board was required before doing so again.
