只有通过EEPROM来改变这个功能。如果你有一个车载UC，你会使用几个GPIO引脚来控制这个部件。一个保持部分复位，另一个引脚控制WP*正常应用是CD和WP都保持低。CRDYPWR需要用于向SD卡供电。记住，这是将SD卡放入已知状态的唯一方法（SD卡上没有复位引脚，因此使用PWR）。

Only method to change that function is via eeprom.
If you have an on board uC you would use a couple of GPIO pins to control the part. One to hold the part
in reset, the other pin to control WP*
Normal application is both CD* and WP are held low.
CRD_PWR needs to be used to supply power to the SD card. Remember that is the only way to put a SD card into a known state (there is no reset pin on a SD Card, hence PWR is used)
