Cyclone III configuration problem

The external conditions for releasing POR are described in the hardware manual. If nSTATUS is low, although it has a correct pullup, I would expect POR condition.

The POR circuit keeps the device in reset state until the power supply voltage levels have stabilized on power-up. Upon power-up, the device does not release nSTATUS until VCCINT, VCCA, and VCCIO of banks 1, 6, 7, and 8 are above the device’s POR trip point. On power-up, VCCINT and VCCA are monitored for brown-out conditions.

A JTAG interface would be generally helpful in further clarifying the issue.
