The pulse width calculating circuit acquires the width of the resetpulse according to the number of the lightened display units.
脉冲宽度计算电路根据被点亮的显示单元的数量,以获得重置脉冲的脉冲宽度。

The output is held low as long as the resetpulse is low. To prevent false triggering, when RESET is not used, it should be connected to VCC.
只要复位脉冲低,输出就低。为防止误触发,当不用“复位“的时候,”复位“端应和Vcc端相连。

Applying a negative-going trigger pulse simultaneously to RESET and TRIG during the timing interval discharges C and reinitiates the cycle, commencing on the positive edge of the resetpulse.
