output pins (nSTATUS and CONF_DONE) and all the JTAG pins in I/O
bank 3 must operate at 2.5 V because the V
I/O banks 1, 2, 3, and 4 support DQS signals with DQ bus modes of × 8.
For × 8 mode, there are up to eight groups of programmable DQS and DQ
pins, I/O banks 1, 2, 3, and 4 each have two groups in the 324-pin and
400-pin FineLine BGA packages. Each group consists of one DQS pin, a
set of eight DQ pins, and one DM pin (see
drives the set of eight DQ pins within that group.
