The HARCRP - Crypto CCA Coprocessor Activity FILE contains a processor type value of "UNKNOWN" for a z14 CPC.
Release: Component: MRMF
The new crypto processor type will be "CEX6C" for the z14 which MICS does not currently identify. There is currently a planned PTF to provide the name for the co-processor, instead of "UNKNOWN". Until the PTF is available that will identify the z14 coprocessor as CEX6C, you can interpret the "UNKNOWN" as "CEX6C".
