 About writing to the DMA related registers

In DMA transfers, data are exchanged via the internal bus. Therefore, make sure the DMA related

registers basically are written to immediately after reset or when transfers are disabled (transfer

enable bit = 0). When transfers are enabled, do not write to the DMA related registers, except for

the DMA transfer enable bit, transfer request flag, and the DMA transfer count register that is

protected against write in hardware. This is necessary to ensure stable operation of DMA transfers.

The table below shows whether DMA related registers can be accessed for write.

✕

Transfers disabled

: Can be accessed; 5: Cannot be accessed

Even for a few exceptional registers that can be accessed for write while transfers are enabled,

make sure the following conditions are met.

①

  DMA Channel Control Register's transfer enable bit and transfer request flag

For all other bits of the channel control register, write the same data as they had before
writing. Note that for the transfer request flag, only writing 0 is effective.

➁

  DMA Transfer Count Register

When transfers are enabled, this register is protected against write in hardware.
Therefore, the data written to this register is ignored.

➂

  Rewriting the source and destination addresses of DMA on other channels by a DMA

     transfer

Although this means accessing the DMA related registers while transfers are enabled, it
may not cause any problem. However, a DMA transfer to any DMA related registers on
the current channel cannot be performed.
