Block Transfer Mode (Cycle Steal Mode): Figure 8.17 shows an example of transfer when
ETEND output is enabled, and word-size, block transfer mode (cycle steal mode) is performed
from external 16-bit, 2-state access space to external 16-bit, 2-state access space.
One block is transferred in response to one transfer request, and after the transfer, the bus is
released. While the bus is released, one or more CPU, DMAC, or DTC bus cycles are initiated.
