各位大侠，问下HY27US08561A，我读取ID是正确的，但读数据出错
如题，读数据是，数据全为0，下面是部分代码！请帮帮忙啊，谢谢！@！！void WrNFCmd(UINT8 CMD)
{
Port_DataOut;
flash_ALEL;
flash_CLEH;
flash_DataOut = CMD;
flash_WEL;
NOP();
flash_WEH;
flash_CLEL;
}
UINT8 RdNFDat(void)
{
UINT8 temp;
Port_DataIn;
flash_CLEL; //命令锁存禁止
flash_ALEL; //地址锁存禁止
flash_REL; //读信号使能
while((flash_RB) == 0);
NOP();
temp = flash_DataIn;
flash_REH;
return temp;
}
void WrNFAddr(UINT8 add)
{
Port_DataOut;
flash_WEH;
flash_CLEL;
flash_ALEH;
flash_DataOut = add;
flash_WEL;
NOP();
flash_WEH;
flash_ALEL;
}
//读数据，只读a区域
void flash_ReadPage(UINT16 page)
{
UINT8 i;
UINT32 temp = 0;
flash_CEL;
//写命令
WrNFCmd(0);////write the first half page
//写地址
WrNFAddr(0);
WrNFAddr(page&0x00ff);
WrNFAddr(page>>8);
//等待芯片Ready
WaitNFBusy();
//读数据
for(i = 0;i<256;i++)
Readbuf = RdNFDat();
flash_CEH;
WaitNFBusy();
}
