PS5, Line 8: 
           : The GPIO_AP_SUSPEND_L pin is used for communication between the AP and
           : EC to confirm the AP's status. When the AP is running normally, it
           : should be high, and when the AP is in sleep mode, it should be low. This
           : way, the EC will know that the system is in sleep mode. Therefore,
           : during the initial boot phase, the GPIO_AP_SUSPEND_L pin needs to be
           : initialized to output high.
> GPIO_AP_SUSPEND_L is supposed to be high in S0, and low in S3. […]
