TOTAL TICKS is the number of times that the system-clock interrupt occurred during the trace interval.
TOTALTICKS是追踪时间间隔过程中发生系统时钟中断的次数。
While it is running, it records the address of the instruction that is being executed every time a system-clock interrupt occurs.
当它运行时，它会记录每次系统时钟中断发生时正在执行的指令的地址。
Then it generates a report that lists how many "ticks" each of these units of code received (how many times a system-clock interrupt occurred when that particular unit of code was running).
然后，它生成一个报告，列出这些代码单元每个获得了多少个“节拍(tick)”(即当代码的特定单元正在运行时发生了多少次系统时钟中断)。
The clock interrupt processing program tests the state of the printer intermittently, and decides whether the printer will be started again.
时钟中断处理程序定时地去查询打印机的状态，决定是否再次启动打印机。
However, in common embedded system, the real-time clock interrupt will wake up the CPU rapidly and periodically even there is no other devices' interrupt. That will increase system power consumption.
但在一般的嵌入式系统中，当系统进入IDLE状态后，即使没有其他设备中断，实时时钟中断也会不断唤醒CPU，这样就会大大增加系统的功耗。
