#define  Write_Read_Addr_offset 0x10000
u8 i;
u8 k=0;
u16 dat[32];
if(Write_Sram_Flag==1)
{
Write_Sram_Flag=0;
for(i=0;i<30;i++)
{
for(k=0;k<32;k++)
{
   dat[k]=i+1;
}
      SRAM_WriteBuffer(&dat[0], i*Write_Read_Addr_offset+(zzz-1)*64, 32);
}
zzz++;
if(zzz>=1000)
zzz=1000;
}
具体现象是testsram26、testsram27、testsram28、testsram29、testsram30的数据和中间一些是对的；有部分数据都被覆盖了，比如testsram8和testsram16的数据都是16，请大神指点下，谢谢
