In the block transfer mode, once transfer starts, the DMAC continues the transfer operation without releasing the
After the block transfer ends and the DMAC releases the bus, another DMA transfer can be acknowledged.
The following shows an example of block transfer in which a higher priority DMA request is issued. DMA channels
