功能描述：

开机后在每1、2位数码管显示00，D8点亮表示目前处于调整地址的状态

此时按S1和S2，第1、2位数码管的数据从00~FF变化

此时若按下S4键，则读出1、2位所示数据作为地址的EEPROM中的值，显示在第5、6



位上

按下S3键，D7点亮，表示进入调整数据状态，此时第5、6位数码管点亮显示值与第



1、2位同

按下S1和S2，第5、6位上的数据从00~FF变化

此时若按下S4键，则将5、6位上的数据写入第1、2位指定的地址单元中-　Functional Descr iption:　at every boot after the 1,2-bit digital tube display 00, D8 light that is currently going through an adjustment of status address　at this time by the S1 and S2, 1,2-bit digital control data from the 00 ~ FF Change　 at this time if the press the S4 key, then read out the data as shown in 1,2-bit EEPROM address of the value displayed in the first place on 5,6　press the S3 key, D7 lit, adjust the data to enter the express status , when the first 5,6-bit digital tube light show value and the first place with 1,2　press S1 and S2, the first 5,6-bit on the data from the 00 ~ FF change　at this time if the press the S4 key, 5,6-bit will be written into the first data on 1,2-bit address specified unit
