3.4 LSS IDENTIFICATION SERVICES
LSS identify remote slave
By means of this service, the LSS master device requests all LSS slave devices to identify themselves by means of the
'LSS identify slave' service, whose LSS address meets the LSS_Address_sel. The LSS_Address_sel consists of a single
vendor-ID and a single product code and a span of revision and serial numbers determined by a low and high number.
The protocol defined in the following figure implements the LSS identify remote slave service. All LSS slave devices
with matching vendor-ID and product-code and whose major revision-number and serial-numbers are located within the
given ranges, identify themselves with the LSS identify slave service. The boundaries are included in the interval.

Product-code is the LSS slave’s identity Product-code (Intel format byte ordering).
Revision number low and Revision number high identity the Revision number span (Intel format byte ordering).
Serial number low and Serial number high identity the Serial number span (Intel format byte ordering).

LSS identify non-configured remote slave
By means of this service, the LSS master device requests all LSS slave devices to identify themselves by means of
the 'LSS identify non-configured slave' service, who got stuck in NMT Initialization state, whose pending node-ID is invalid
(FFh) and who have no active node-ID.
