1. If the DAD bit in the DMiCON register is 0 (fixed), this register can only be written to when the DMAE bit in the
DMiCON register is 0 (DMA disabled).
If the DSD bit is 1 (forward direction), this register can be written to at any time.
If the DSD bit is 1 and the DMAE bit is 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 source address of transfer
Nothing is assigned. If necessary, set to 0.
When read, the content is 0.
Set the destination address of transfer
Nothing is assigned. If necessary, set to 0.
When read, the content is 0.
