门控位GATE1可使定时器/计数器的启动受INT1非的控制,当gate=1,TR1=1时,
只有INT1非的引脚输入高电平时,T1才被允许计数。利用这个特征,来测量方波的
半个周期-Gated GATE1 enable bit timer/counter activated by the control of non-INT1, when gate = 1, TR1 = 1, only non-INT1 pin high when the input, T1 was allowed to count. Use of the characteristics to measure the half-cycle square wave
