本程序运行时,按下K1将向EEPROM中写入1~21,按下K2时写入无规律的21个数,按下K3时读取EEPROM中的21个数并循环显示.所读写的21个数中,前20个在EEPROM中的地址是透明的(0x0001~0x0014),最后的第21个数其地址是不透明的.-This program is running, press K1 will be 1 to 21 is written in the EEPROM, when writing press K2 irregular number 21, press K3 in the EEPROM 21 is read and the cycle number. The reader number 21, the first 20 addresses in the EEPROM is transparent (0x0001 ~ 0x0014), the final number of the address of the first 21 is opaque.
