29.5.3.3.7 Resume Execution (
The pipeline is flushed and refilled before normal instruction execution resumes.
Prefetching begins at the current address in the PC and at the current privilege level. If any
register (such as the PC or SR) is altered by a BDM command while the processor is halted,
the updated value is used when prefetching resumes. If a
CPU is not halted, the command is ignored.
