    DMAC Setting that allows transfers to be repeated without instruction from CPU.

    JuIn_1625121

      The customer wants to use DMA transfer with these settings.

       

      DMACB:
      EM=1 (Dose not clear DMACA:EB bit (bit31) upon completion of the transfer.)
      RC=1 (Enables the reload function of BC/TC.)
      RS=1´╝łEnables the reload function of the transfer source address.)
      RD=0 (Enables the reload function of the transfer destination address.)

       

      Can he set?

       

      There is the description on the manual.
      "This function can only be used for hardware transfer. To use the function, enable the reload function of RC, RS and
      RD bits."
      Is it a rule that must be obeyed?

       

      Best regards,

      Inoue
