+ help
+ On the real chip of the NPS, auxiliary registers are shared between
+ all the cpus of the core, whereas on simulator platform for NPS,
+ each cpu has a different set of auxiliary registers. Configuration
+ should be unset if auxiliary registers are not shared between the cpus
+ of the core, so there will be a need to initialize them per cpu.
