Hardware Installation
The General Purpose Input/Output (GPIO) peripheral provides dedi-
cated general-purpose pins that can be configured as either inputs or
outputs. When configured as an output, you can write to an internal
register to control the state driven on the output pin. When
configured as an input, you can detect the state of the input by
reading the state of an internal register.
ICH_GPIO 6/7/38/39 is the main power used for GPIO output.
ICH_GPIO 12/13/14/15 is the resume power used for GPIO input.
