/*
|
|||
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 |
