Each I/O pin has the circuitry shown in
not include CONF_DONE, nCEO, and nSTATUS pins to ensure that they are able to
operate during configuration. Thus, it is expected behavior for these pins to drive out
during power up and power down sequences.

family.
The POR circuit monitors the voltage level of power supplies and keeps the I/O pins
tristated until the device is in user mode. The weak pull-up resistor (R) in Cyclone III
device family I/O element (IOE) keeps the I/O pins from floating. The 3.0-V tolerance
control circuit permits the I/O pins to be driven by 3.0 V before V
supplies are powered up, and it prevents the I/O pins from driving out when the
device is not in user mode.
Altera uses GND as reference for hot-socketing operation and I/O buffer designs. To
ensure proper operation, Altera recommends connecting the GND between boards
before connecting the power supplies. This prevents the GND on your board from
being pulled up inadvertently by a path to power through other components on your
board. A pulled up GND can otherwise cause an out-of-specification I/O voltage or
current condition with the Altera
