Stratix II devices have a POR circuit to keep the whole device system in
reset state until the power supply voltage levels have stabilized during
power-up. The POR circuit monitors the V
levels and tri-states all the user I/O pins while V
normal user levels are reached. The POR circuitry also ensures that all
eight I/O bank V

continues to monitor the V

sag below the Stratix II operational level during user mode, the POR
circuit resets the device.
