The POR circuit monitors the voltage level of power supplies (V
and V
pull-up resistor (R) in the Stratix III input/output element (IOE) keeps the I/O pins
from floating. The 3.3-V tolerance control circuit permits the I/O pins to be driven by
3.3 V before V
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, you must connect the GND between boards before
connecting the power supplies. This will prevent 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 could otherwise cause an out-of-specification I/O voltage or
current condition with the Altera device.
