Internal Weak Pull-Up Resistor
Table 2-15: Internal Weak Pull-Up Resistor for Arria V GZ Devices
All I/O pins have an option to enable the weak pull-up resistor except the configuration, test, and JTAG pins. The internal weak pull-down feature is only
available for the JTAG TCKpin. The typical value for this internal weak pull-down resistor is approximately 25 kΩ .

The I/O ramp rate is 10 ns or more. For ramp rates faster than 10 ns, |IIOPIN| = C dv/dt, in which C is the I/O pin capacitance and dv/dt is the slew
rate.

The pin pull-up resistance values may be lower if an external source drives the pin higher than VCCIO
These specifications are valid with a 10% tolerance to cover changes over PVT.
