SSTM (2eSST Mode): This field defines the 2eSST Transfer Rate.
Table 154: 2eSST Transfer Rate
TM (Transfer Mode): This field defines the VMEbus transfer mode.
Table 155: VMEbus Transfer Mode
DBW (VMEbus Data Bus Width): These bits define the maximum data bus width for
VMEbus transfers initiated by the DMA controller. These bits apply to SCT and BLT
transfers. MBLT, 2eVME and 2eSST transfers are always 64-bit.
