Question

Does PORSEL pin exist in Arria II GX?

In device pin connection Gideline,PORSEL exists in a space og Arria II GZ name,but NAexists in a space og Arria II GX name.

In table9-5 of arria II device handbook,there is following description in a space of Arria II GX.

VCCPD and VCCIO for I/O banks 3C and 8C must ramp up from 0 V to the desired

voltage level within 100 ms when PORSEL is low or 4 ms when PORSEL is high.

Which is right?

The above mentioned description doesn't show that B exists in A.

There is contradiction in 2 of above mentioned description, so I don't find out that PORSEL exists in arria II GX.

2 of sentences are inconsistent.

So I can't understand whether PORSEL exists in Arria II GX.

For Arria II GX devices, the POR time selection depends on the MSEL pin settings. There is no PORSEL pin in Arria II GX.

For Arria II GZ devices, the POR time selection depends on the PORSEL input pin.
