Set Condition Location Command
The set_cond_loc command takes a single parameter that controls the conditional test return value for requests
either from the PE requests or the DPP. If the location is set to the DPP, the CO always returns true to the PE and
performs the conditional test for any DPP request. Conversely, if the location is set to the PE, the CO always returns
true to the DPP and performs the conditional test for any PE request. The location is maintained until the next
