SCI multi-buffer mode timeout interrupt

Other Parts Discussed in Thread: TMS570LS20216

Hello,experts:

        I'm using TMS570LS20216 do some functions test about SCI, I have a question like this:

        I use SCI multi-buffer mode to transmit and receive data(receive interrupt enabled), the character length is 8 bit, and   the response field has 8 characters., when receiving data frame is 8 bytes length, the interrupt can be triggered and I can read the data frme correctly, but when the data frame is less than 8 bytes, the interrupt can not be generated, and the receive data still in the buffer.I see the TRM 13.4.4 Error Interrupts, it seems that the SCI mode does not support  timeout interrupt, it's that ture?How should I do for this situation?
