1、在熔丝位设置一旦选择了外部晶振后，那个OSC根本就不起振，怎么可能给EEPROM提供时钟？
2、在“AVR Clock Control Unit ”有一根“clkFLASH”时钟通到FLASH和EEPROM，那才是给EEPROM用的时钟；
3、至于——Note that this oscillator is used to time EEPROM and Flash write accesses, and these write times will be affected accordingly...
个人认为也是笔误，应该改为：
Note that when this oscillator is selected as device clock source by setting CKSEL3..0 to 0100 - 0001,it is also used to time EEPROM and Flash write accesses, and these write times will be affected accordingly.... |
