(6) Specification of a micro DMA burst
Specifying the micro DMA burst function causes micro DMA transfer, once started, to
continue until the value in the Transfer Counter Register reaches zero. Setting any of the bits in
the register DMAB which correspond to a micro DMA channel (as shown below) to 1 specifies
that any micro DMA transfer on that channel will be a burst transfer.
