what's the application of sequential transmission of I2C in HAL library in STM32f746ng

Question

I can understand that you can use first frame option for first frame and next frame options for others, but since you can use them as FIRS_FRAME_LAST_FRAME, what is the advantage of other? and when we must use them?

Findings: A code use wile to continuously transmit two number and get a callback to see if module has accepted that, if this happen correctly the led must blink.

In this simple code I've tested every xferoption of sequential transmission, every options worked except: I2C_LAST_FRAME_NO_STOP and I2C_FIRST_FRAME. Code:

while (1)
  {
      value=300;
      *(uint16_t*) buffer=(value<<8)|(value>>8);//Data prepared for DAC module
      HAL_I2C_Master_Seq_Transmit_IT (&hi2c1, (MCP4725A0_ADDR_A00<<1), buffer, 2,I2C_LAST_FRAME_NO_STOP);
      HAL_Delay(1);
      HAL_I2C_Master_Receive(&hi2c1, (MCP4725A0_ADDR_A00<<1), rxbuffer, 3, 1000);
      if( (uint16_t)(((uint16_t)rxbuffer[1])<<8|((uint16_t)rxbuffer[2]))>>4 == value ){
          HAL_GPIO_WritePin(LED_GPIO_Port,LED_Pin,GPIO_PIN_SET);}

      HAL_Delay(50);

      value=4000;
      *(uint16_t*) buffer=(value<<8)|(value>>8);
      HAL_I2C_Master_Seq_Transmit_IT (&hi2c1, (MCP4725A0_ADDR_A00<<1), buffer, 2,I2C_LAST_FRAME_NO_STOP);
      HAL_Delay(1);
      HAL_I2C_Master_Receive(&hi2c1, (MCP4725A0_ADDR_A00<<1), rxbuffer, 3, 1000);
      if( (uint16_t)(((uint16_t)rxbuffer[1])<<8|((uint16_t)rxbuffer[2]))>>4 == value ){
          HAL_GPIO_WritePin(LED_GPIO_Port,LED_Pin,GPIO_PIN_RESET);}

      HAL_Delay(50);
}
