Integrated Pull-Ups and Pull-Downs

All GPIOs have programmable internal pull-up / pull-down resistors (20 Kohm) which are disabled 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 Info) for more details. The internal pull-up / pull down can only be implemented if the toggle rate of the GPIO is no more than 300 kHz.

Note:Certain GPIOs used as pin straps have internal PU / PD enabled during reset by default.

Refer to the GPIO Implementation Summary document (# 616476) for information on which GPIO has integrated PU / PD enabled during reset.
