Reads the specified thread real-time configuration register from a specified PSI-L thread using the PSI-L configuration proxy. The host requesting the read operation for threads mapped to UDMAP channels must be the owner, or the supervisor of the host owning, the UDMAP channels. For threads not mapped to UDMAP channels, the host requesting the read operation must have access through the region firewall covering the entity to which the thread is mapped. The PSI-L configuration proxy used to read thread's configuration registers is based on the Navigator Subsystem specified by nav_id.
