I disasmed pops prx,found they are using it.

0xA0000000 is uncached kernel space, so your question is REALLY "what is at 0x00000000?"

On the ME, that is local EDRAM (2MB on the Phat, 4MB on the slim). On the SC, that is nothing... however, there is scratch ram at 0x00010000 (16 KB), so double-check your addresses.

0xa = (8 | 2)

So maybe it's some kind of uncached kernel address? Probably ME, I guess. Check this:

Thanks.
Seems it's ME's region.
