Open drain

Hello,

technical reference in “9.12.1 Pads in Open Drain Mode” says “Both the ST pads and DD pads can operate in Open Drain Mode. But the DD pads have specific control to tolerate the IO swing of 3.3 V.”

but from “Table 23: Pad Details and Controls” looks like ST pads doesn’t support open drain mode.

What is true?
Can be ST pads GPIO03, GPIO04, GPIO05 set to open drain mode?

Which doc do you mean?

Tegra X1 SoC Technical Reference Manual (tegra-x1-technical-reference-manual.pdf)

on the page: Support Resources | NVIDIA Developer > Jetson Nano section: SoC Technical Reference Manual

ST pins can be used as OD mode.

thank you.
How can I setup it?
pinmux template (NV_Jetson_Nano_Module_Pinmux_Config_Template.xlsm) doesn’t have OD mode.

any help, please?

Hi, we are still checking if ST pads can be used as OD mode. Will update once available.
