To exit from Debug state, scan in the Restart instruction through the ARM1156T2-S DBGTAP. You might want to adjust the PC before restarting, depending on the way the integer unit entered Debug state. When the state machine enters the Run-Test/Idle state, normal operations resume. The delay, waiting until the state machine is in Run-Test/Idle, enables conditions to be set up in other devices in a multiprocessor system without taking immediate effect. When Run-Test/Idle state is entered, all the processors resume operation simultaneously. The core restarted bit is set when the Restart sequence is complete.
