Normally, ALE with clock frequencies are 1/6 output pulse signal with fixed, so it can be used for th
18、e purpose or output clocks. Timing Those who want an attention is: whenever access to external numerical memory will skip a ALE pulse.For FLASH memory programming, this pin is used for input programming pulse (.)
