(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.
