如題，CH438Q，讀寫數(shù)據(jù)時(shí)序問題，時(shí)鐘無法使INI#拉低

讀寫寄存器代碼如下：

UINT8?ReadCH438Data(?UINT8?addr?)
{
????u8?value;
????CH438_DATA_PORT->ODR?=?(CH438_DATA_PORT->ODR&0XFF00)|addr;
????CH438_ALE_HIGH;
????CH438_CS_LOW;
????CH438_ALE_HIGH;
????CH438_ALE_LOW;
????CH438_DataPin_IN();
????CH438_RD_LOW;
????CH438_RD_LOW;
????value?=?(uint8_t)CH438_DATA_PORT->IDR;
????CH438_RD_HIGH;
????CH438_ALE_HIGH;
????CH438_CS_HIGH;
????CH438_DataPin_OUT();
????return?value;
}

void?WriteCH438Data(?UINT8?addr,?UINT8?dat)
{
????CH438_DATA_PORT->ODR?=?(CH438_DATA_PORT->ODR&0XFF00)?|?addr;?
????CH438_ALE_HIGH;
????CH438_CS_LOW;
????CH438_ALE_HIGH;
????CH438_ALE_LOW;
????CH438_DATA_PORT->ODR?=?(CH438_DATA_PORT->ODR&0XFF00)?|?dat;?//??????
????delay_us(1);
????CH438_WR_LOW;
????CH438_WR_HIGH;
????CH438_ALE_HIGH;
????CH438_CS_HIGH;
????CH438_DataPin_OUT();
}
