General Purpose Input and Output

The PCH General Purpose Input/Output (GPIO) signals are grouped into multiple groups (such as GPP_​A, GPP_​B, and so on) and are powered by either the PCH Primary well or Deep Sleep well.

The high level features of GPIO:

  • Per-group configurable 3.3 V or 1.8 V voltage, except for GPD group (3.3 V only), GPP_​J (1.8 V only), and GPP_​S (1.8 V only)
  • Configurable as an GPIO input, GPIO output, or native function signal.
  • Configurable GPIO pad ownership by host, Intel® CSME, or ISH.
  • SCI (GPE) and IOAPIC interrupt capable on all GPIOs
  • NMI and SMI capability capable (on selected GPIOs).
  • PWM, Serial Blink capable (on selected GPIOs).
  • Programmable hardware debouncer (on GPD3/PWRBTN# pin)
