      Hi,

       

      At first, 16-bit data is transfered from 16-bit transmit data buffer on the RAM to TDR by using DMAC. Transfer width is 16-bit.

      Next, 8-bit data is transfered from 8-bit transmit data buffer on the RAM to TDR by uing DMAC. Transfer width is 8-bit.

      In this case, what values are in 8-bit high register(especially, D8)?

       

      The customer assumes three answers.

      a)0
      b)Indefinite value
      c)datas written at first.

      d)others

       

      Best Regards,

      Inoue
