Jetson Orin Nano Sleep State

What is the pin state of the Jetson Orin Nano while it is in it’s sleep mode (when MOD_SLEEP is low)?

Is SYS_RST still pulled up?

Is it safe to expose the IOs of the module to their IO voltage? For example, external pullup to 1.8V on the GPIO line?

How about other interfaces such as HDMI, USB, PCIe .etc

In deep sleep mode, only the pins that are supplied by VDD_RTC and *_AON (always on) power domain can keep status. Other pins are powered off. You can find the power domain of each pin in pinmux sheet. For interface pin design, please follow the reference.
