Ignition Power Management Quick Guide
Startup/shutdown conditions from the IGNITION signal:

IGNITION startup signal must be valid during 3 sec. (anti noise protection).

IGNITION shutdown – IGNITION signal must be inactive during 3 Sec, then PIC
controller initiate Power Button signal ( OS must be set to shutdown from the
Power Button ). It generates Main Button shutdown event and then goes to
complete power off.
Typically, the system can start only from IGNITION signal, because startup PIC
controller is disconnected from the power source.
The system can be switched off from:

Power IGNITION OFF signal.

ACPI OS shutdown

Power Button – generate ACPI event (OS dependent).
