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.
|
