5.4.2.3 Power OFF -> Power ON (Auto-Power-On Case)
When the user connects the main power source, the MCU sends the power enable signals to
the module (
VIN_PWR_ON) and enables MODULE_POWER_ON. This is accomplished by having the
ACOK signal driven high instead of pulled to
GND.
The signal representing the power button to Jetson AGX Xavier (
POWER_BTN_N) will continue
following the power button (
BUTTON_POWER_ON*) behavior. However, once the power ON
sequence is initiated by the connection of the main power source, and ACOK is driven high (by
push-pull driver powered from 3V3_AO), the power button signals will not affect the MCU
behavior until the
PWR_GOOD signal verification is complete.
