WebProcessing method for RTT: When entering the critical zone, the system shuts down an interrupt (closing all interrupts except NMI FAULT and hard FAULT) immediately after adding the number of entries rt_scheduler_lock_nest to 1. The system resources consumed here are negligible and have little impact on other interrupts in the system.
