Hello ,

I try to make Flexcan's message buffer[0~5] to become a fifo and to consecution receive five data frame.

compute software send five consecution data frame ,using this fifo to receive five consecutive standard data frame,and through check  interrupt  flag1 BUF6I to  check the fifo is almost full .

in my test ,i find only message buffer[0] has data ,message buffer[1~4] has no data. the interrupt flag1 bit is setting 1.
