chinatiger

hi, experts:

通过DBGDRCR.HRQ：可以让CPU进入halting debug state.

执行hlt指令：是否也能让CPU进入halting debug state?

best wishes,

    可以让cpu 进入 halting debug mode 的 方式包括：

    • a breakpoint hits
    • a watchpoint hits
    • a BKPT instruction is executed
    • the EDBGRQ signal is asserted
    • a Halt instruction has been scanned into the DBGTAP instruction register
    • an vector catch occurs.
