本程序用于测试实时时钟模块SD2000的SRAM存储器D/E系列， 程序功能如下： 1. 关闭/INT1及/INT2的中断输出 2. 初始化时间(写时间数据) 3. 在BREAKPOINT1设断点时,依次读时间-写SRAM数据-读SRAM数据循环 4. 全速执行时,LED四位分别显示小时和分钟的值-procedures used to test the real-time clock module SD2000 SRAM memory D / E Series, procedures follo

of the electrical power system. At the time of transformer energization high current is drawn by the transformer known as the inrush current. This current is nearly ten times more than the full load current of transformer. It produces mechanical stre
