At the beginning of the program,
I first performed a write-then-read operation on register 00 using I²C timing.
I wrote 0x04 to register 00, and this worked correctly.
However, when I used the same method to perform a write-then-read operation on register 03,
I wrote 0x07 to register 03,
but when I read register 03, the returned value was 0x08.
Can you tell me why this problem might occur?
What are the possible reasons?

I found out why.
so i should init first：
