读取ad9648的某些寄存器值不准确。请问是我的设置有问题还是IC有问题？我通过SPI写一个寄存器，然后发送0xff、0x01。我写0x03或者0x17写0x81到0x05是正确的，但是很多时候读的时候就不正确

Reading some register values of ad9648 is inaccurate. Is there a problem with my settings or with the IC? I write a register via SPI and send 0xff, 0x01. When I write 0x03 or 0x17, it is correct to write 0x81 to 0x05, but many times it is incorrect when reading.

这是我写0x81到0x17，读取结果是0x81，正确

This is when I write 0x81 to 0x17, the read result is 0x81, correct

这是我从寄存器0x01读取的内容，其结果应该是0x88。我应该怎么办？

This is what I read from register 0x01, the result should be 0x88. what should I do?
