MCS-96单片机A_D转换器应用-通过检测AD_RESULT（LO）中的S位来判定A/D转换是否完成。需要注意的是，当发出启动A/D转换命令后，AD_RESULT中的S位要经过8个状态周期后才能对其查询.-MCS-96 microcontroller A_D converter applications-through detection AD_RESULT (LO) the S to determine A / D converter whether completed. We need to be aware that when issued start A / D conversion orders, AD_RESULT the S-8 to go through cycle after the state of its inquiries.
