Hardware Installation
GPIO Connector
The General Purpose Input/Output (GPIO) peripheral provides dedicated 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 in-
put 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.
