Internal Weak Pull-Up Resistor

All I/O pins, except configuration, test, and JTAG pins, have an option to enable weak pull-up. For SDM and HPS, the configuration I/O and peripheral I/O are supported with weak pull-up and weak pull-down options. The internal weak pull-down feature is only supported in selected HPS and SDM I/O. The typical value for this internal weak pull-down resistor is approximately 25 kΩ.
