Enhanced Serial Peripheral Interface
####################################

Overview
********

This sample demonstrates how to use the Enhanced Serial Peripheral Interface
(eSPI) API.
It shows how to configure and select eSPI controller capabilities as part of
a simple eSPI handshake that includes exchanging virtual wire packets.

Standard platform signals are sent virtual wire packets over the bus.
Callbacks are registered that will write to the console indicating main
eSPI events and when a virtual wire is received.

Building and Running
********************

The sample can be built and executed on boards supporting eSPI.
Any pins required for minimum eSPI handshake should be configured.

Sample output
