说明：  24Cxx I2C EEPROM字节读写驱动程序，芯片A0-A1-A2要接GND(24C65接VCC,具体看DataSheet)。 现缺页写、页读，和CRC校验程序。以下程序经过50台验证，批量的效果有待考察。 为了安全起见，程序中很多NOP是冗余的，希望读者能进一步精简，但必须经过验证。 Atmel 24C01 比较特殊,为简约型,为其单独编程
(24Cxx I2C EEPROM byte read and write driver, Chip A0-A1-A2 access to GND (24C65 then VCC, DataSheet specific view). Na pages are written, page reading, and CRC procedures. After following procedures of 50 test batch of results to be inspected. For security purposes, many NOP process is redundant, and hope that readers will be further streamlined, it must be tested. Atmel 24C01 rather special type of minimalism, as a separate program)
