General Purpose Input and Output

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

The high level features of GPIO:

  • 1.8 V operation (including the muxed functions on the pin).
  • Integrated pull-up / pull-down.
  • Configurable as GPIO input, GPIO output, or native function signal.
  • Configurable GPIO pad ownership by host, 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).
