nRF52832 with ms5803 via I2C communication

Question

Hello! I'm using nRF52832 with ms5803-14BA.

And I want to get this sensor's raw data form prom.

and my code is here

#include <stdio.h>
#include "boards.h"

#include "app_error.h"

#include "nrf_log_ctrl.h"
#include "nrf_log_default_backends.h"

    APP_ERROR_CHECK(err_code);
    while (m_xfer_done == false);

    
}

I don't know why the resultant value is 65535(which is 16bit saturation)

HELP ME ㅠㅠ
