/*
|
|
EEPROM 的写操作只能将字节中的 1 写为 0，当需要将字节中的 0 写为 1，则必须执行扇区 擦除操作。
|
|
EEPROM 的读/写操作是以 1 字节为单位进行，而 EEPROM 擦除操作是以 1 扇区（512 字节） 为单位进行，
|
|
在执行擦除操作时，如果目标扇区中有需要保留的数据，则必须预先将这些数据读取到 RAM 中暂存，
|
|
待擦除完成后再将保存的数据和需要更新的数据一起再写回
|
|
EEPROM Write operation can only write 1 in the byte as 0, when you need to write 0 in the byte as 1,
|
|
you must be sector erased. EEPROM Read / write operation is conducted in 1 byte,
|
|
while EEPROM, erasure operation is conducted in 1 sector (512 bytes). During the wipe operation,
|
|
if the data in the target sector, the data must be read in the RAM in advance,
|
|
and the saved data will be written back together with the data to be updated
|

fixme：注意时钟和flash 相关 同时关注掉电和容错
