关于PIC单片机的定时计数器的一端源程序。定时功能就是通过来自单片机内部的时钟脉冲作计数脉冲，使计数器计数，即每个机器周期计数器加1，计数值达到予置值后，定时/计数模块产生溢出。-One end of the source code on the PIC microcontroller timing counter. The timing function is passed from the internal microcontroller clock pulse count pulse, so that the counter of every machine cycle counter is incremented, the count value reaches the value I set, timer/counter module overflow.
