POWER_ON Power button & SC7 wake interrupt
Module power configuration
identification. Tied to GND on Jetson
− TX2i. Floating on Jetson TX2.
Determines the power-on mechanism
used to support both Jetson TX2 & TX2i.
Power Button. Used to initiate a system
power-on. Connected to PMIC EN0
which has internal 10KΩ Pull-up to
POWER_ON / (PMIC
VDD_5V0_SYS. Also connected to Tegra
EN0)
POWER_ON pin through Diode with
100kΩ pull-up to VDD_1V8_AP near
