Electrical Characteristics
Internal Weak Pull-Up Resistor
Table 13 lists the weak pull-up resistor values for Arria V devices.
All I/O pins have an option to enable weak pull-up except the configuration, test, and
JTAG pins. For more information about the pins that support internal weak pull-up
and internal weak pull-down features, refer to the Arria V GT, GX, ST, and SX Device
Family Pin Connection Guidelines.

Notes to Table 13:
(1) Pin pull-up resistance values may be lower if an external source drives the pin higher than VCCIO
(2) Valid with 10% tolerances to cover changes over PVT.
