The DPS field has no meaning or effect on memory-to-memory transfers.
To access on-chip peripherals, the transfer size (TrSiz) must be equal to the device port size (DPS).
The CCRn register must be programmed before placing the DMAC in Ready state.

Reset value = 0
Controls whether or not to request bus mastership with snooping. If set, the TX19
core processor’s snoop function becomes valid, allowing the DMAC to use the
processor’s data bus. If cleared, the snoop function is disabled.
1: The snoop function is enabled (i.e., SREQ is used as a bus request signal).
0: The snoop function is disabled (i.e., GREQ is used as a bus request signal).
Reset value = 0
Controls whether or not to respond to the bus release request signal from the TX19
core processor. This bit is valid when the DMAC uses GREQ as a bus request signal.
This bit has no meaning or effect when the DMAC uses SREQ as a bus request
signal because, in that case, the TX19 core processor does not have the capability to
generate a bus release request signal.
1: The DMAC will respond to the bus release request signal from the TX19 core
0: The DMAC will ignore the bus release request signal from the TX19 core
Reset value = 0
Specifies the type of the source device.
1: I/O device
0: Memory
Reset value = 00
Selects the manner in which the source address changes after each cycle.

Reset value = 0
Specifies the type of the destination device.
1: I/O device

Reset value = 00
Specifies the amount of data to be transferred in response to a DMA request.
11: 8 bits (1 byte)
10: 16 bits (2 bytes)
0x: 32 bits (4 bytes)
Reset value = 00
Specifies the port size of a source or destination I/O device.
