把DEV_OVUV1寄存器15-12位1000更改为1001,然后DEV_EE_CTRL1寄存器写入0xA7,断电上电后写入0xA2,DEV_OVUV1 15-12位并没有被置为1001,不知道这存在什么问题?
Kailyn Chen:
您好不知您的问题解决了没?寄存器写不进去,是否有对EEPROM进行解锁? 因为 datasheet中有这样描述:To perform EEPROM operations as EEPROM programming and EEPROM reloading, the EEPROM usermemory space must initially be unlocked.Table6给出了unlock EEPROM的顺序。www.ti.com/…/pga411-q1.pdf
