4. IGNITION POWER MANAGEMENT
Startup/shutdown conditions from the IGNITION signal:
• IGNITION startup signal must be valid during 5 sec. (anti noise protection).
• IGNITION shutdown – IGNITION signal must be inactive during 5 minutes,
then PIC controller initiate Power Button signal (OS must be set to shutdown
from the Power Button). It generate 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).
