    For GPIO_REG description, it is clear that these only can be used as local GPIO.
    But, due to these pins also are reused as I2S pins, so you can use I2S transmit mode to send the expected data in these pins from UB927 to UB928. To use this function, you should have clock (1M~10M) in the I2S_CLK pin.
