If the DAD bit is set to “1” (forward direction), this register can be written to at any time.
If the DAD bit is set to “1” and the DMAE bit is set to “1” (DMA enabled), the DMAi forward address pointer can be
read from this register. Otherwise, the value written to it can be read.

Set the transfer count minus 1. The written value is
stored in the DMAi transfer counter reload register,
and when the DMAE bit in the DMiCON register is
set to “1” (DMA enabled) or the DMAi transfer
counter underflows when the DMASL bit in the
DMiCON register is “1” (repeat transfer), the value
of the DMAi transfer counter reload register is
transferred to the DMAi transfer counter.
When read, the DMAi transfer counter is read.
Set the destination address of transfer
Nothing is assigned. When write, set “0”. When read, these contents
are “0”.
Set the source address of transfer
Nothing is assigned. When write, set “0”. When read, these contents
are “0”.
