pin 6: power down - external power down input. inactive if not connected or less than 0.5v. active if greater than 2.7v. typical switch point is 2.0v @ 0.34 ma. input impedance is 15k ohms. activation of this input powers the internal regulators off and drops
the supply current below 20ma in the -lvx version and below 1ma in the
-hvx version. the computer will be reset when power is restored.
是不是该脚有高于2.7v的电压就打开电源了
