使用复杂度相对于330、340又上了一个档次。一个
void WriteFlashByte(unsigned char xdata *address, unsigned char value)
{
    data unsigned char xdata *pwrite;
    pwrite = (unsigned char xdata *)address;
    EA = 0;
    SFRPAGE   = 0x0F;
    CCH0CN &= 0xFE;
    SFRPAGE   = 0x00;
    FLKEY = 0xa5;
    FLKEY = 0xf1;
    PSCTL &= (~0x02);
    PSCTL |= 0x02;
    SFRPAGE   = 0x0F;
    *pwrite = value;//7.用MOVX指令向扇区内的目标地址写入一个数据字节
    _nop_();
    SFRPAGE   = 0x00;
    PSCTL &= 0xFE;
    EA = 1;
}
程序，竟然不能兼容其自己的MCU。唉
