A. Power Sequencing Logic When you press the power button on a laptop, the main CPU is not yet running. The IT8995E initiates the boot sequence: | Parameter | Symbol | Min | Typ

B. ACPI Compliance The chip implements an ACPI Embedded Controller interface. The Operating System (Windows/Linux) uses ports 0x62 (Data) and 0x66 (Command/Status) to talk to the IT8995E. This allows the OS to query: 4 tach | 4 PWM
