The POR circuit monitors V
tri-stated until the device is in user mode. The weak pull-up resistor (R)
from the I/O pin to V
tolerance control circuit permits the I/O pins to be driven by 3.3 V before
V
driving out when the device is not in user mode.
For more information, see the DC Characteristics & Timing Specifications
chapter in Volume 1 of the Cyclone II Device Handbook for the value of the
internal weak pull-up resistors.
