29 Branch Trace Functions: The branch s ource and desti nation addr esses , their source lines, branch types, and types of acces sed bus mast ers are displayed.
30 Range Memory Access T race Functions: The memory access within the specified range is acquired by a trace. The rea d cycle, write cycle, or read/write cycle can be se lected as the bus type, ASID value, or bus cycle for trace acquisition.
31 (iii) Open the [ASID] page, remove the check mark of the [Don’t care] check box, and enter the ASID value to b e set. When the ASID val ue is not se t as a condition, do not remo ve the check mark of the [Don’t care] check box.
