错误和异常主要的区别在于是否需要脚本的编写者进行处理。对于错误,通常是脚本本身的问题或者是系统的运行环境不符合预期,这种时候停止脚本的运行是更加妥当的选择。而异常则是需要脚本处理的问题,如curl请求失败、文件操作无权限等等。 不过Shell脚本本身并没有明确的区分错误和异常,只有返回码(exit code)用于判断程序执行...

处于Capture-IR状态时,指令寄存器中的值被固定设置成0b0000001,并将它放入连接在TDI与TDO之间的移位寄存器中。 处于Capture-DR状态时,指令不会被改变。 如果TMS信号在下一个TCK上升沿处于高电平,TAP进入Exit1-IR状态;如果TMS信号在下一个TCK上升沿处于低电平,则TAP进入Shift-IR状态。
