/*CH584具有data_flash和code flash两部分。 codeflash为448k dataflash为32k

CodeFlash读操作是有硬件加扰的，也就是擦除后读不是全FF，而是四个固定字节的循环，DataFlash读操作没有硬件加扰
|

CodeFlash和DataFlash都可以直接指针读数据(指针读经过硬件加扰)。

/*BLE蓝牙falsh写入注意地址是相对于dataflash的，而dataflash的起始地址是0x3FFF，所以传入的参数是0x3FFF+offset

接口中的读/写buff缓存在ram中的地址，一定要4字节对齐，否则可能导致hardfault复位
