Integrated Pull-ups and Pull-downs

All GPIOs have programmable internal pull-up/pull-down resistors which are off by default. The internal pull-up/pull-down for each GPIO can be enabled by BIOS programming the corresponding PAD_​CFG_​DW1 register. Refer to Volume 2 (Register Information) for more details.

Note:All GPP groups support the programmable pull-up or pull-down of 20 kohm, except for GPP_​S group, which only supports the programmable pull-up or pull-down of 5 kohm.
