5 Use eSPI to connect to a slave device and exchange virtual wire packets.
11 (eSPI) API <espi_api>`.
12 It shows how to configure and select eSPI controller capabilities as part of
13 a simple eSPI handshake that includes exchanging virtual wire packets.
17 eSPI events and when a virtual wire is received.
22 The sample can be built and executed on boards supporting eSPI.
23 Any pins required for minimum eSPI handshake should be configured.
25 Please connect an eSPI device to the testing board.
