Explaination
Isolated modules are used for de-/encryption, rehashing etc.
Commonly found in CoreOS, dev_flash, embedded sony selfs and service packages like Remarry Bluray Drive.
They are SPU .self binaries which can be called whenever needed: e.g. decrypting and hashcheck EID0 for Target ID inside IDPS when called upon by lv1 (HyperVisor) to set up restrictions for Retail/CEX or Debug/DEX etc.

sc_iso.self
sc_iso.self is used by the system to handle communications to/from syscon. Once debug printing is enabled after you load it, you can see some of the internal workings including error codes for when you are trying to use the module on your own.
