The transfer source bit width must be an integral multiple of the transfer destination bit
width.
Specifies the total number of transfers when the DMAC is operating as a flow controller.
The <TransferSize> value decrements with respect to each DMA transfer until it reaches 0.
On read, the number of transfers yet to be performed is read.
The total transfer count should be specified in units of the transfer source bit width.

<SBSize[2:0]>
Examples:
<Swidth>
8 bits
16 bits
32 bits
If the transfer source bit length is smaller than the transfer destination bit length, caution is required in
specifying the total transfer count. Make sure that the following equation is satisfied.
Transfer source bit length
N: Integer
