INA231: Cannot write

Part Number: INA231

Dear all:

        We have a project that USES TI INA231. The CPU reads and writes registers through the I2C interface. During debugging, it is found that the read operation is OK.But there is a problem with the write operation. There is no way to write it in.What should I do?

        Looking at DS, this seems to be an address corresponding to 2 bytes (16bit). Do you have any special requirements for this writing and normal I2C operation?

Thank you!
