Feel that you are around, is not divided into the pulse.
感觉你在左右，就是分不开的脉搏。

Programmable hardware timing was used in design of microsecond synchronizer based on ISA bus, after pulse generated by oscillator was divided frequency, it was sent to 8254 to count.
基于IS A总线的微秒级同步器采用可编程硬件定时，由晶振发出脉冲经分频后送入8254计数。
