Normal Transfer Mode (Cycle Steal Mode): Figure 8.15 shows an example of transfer when
ETEND output is enabled, and word-size, normal transfer mode (cycle steal mode) is performed
from external 16-bit, 2-state access space to external 16-bit, 2-state access space.
After one byte or word has been transferred, the bus is released. While the bus is released, one
CPU, DMAC, or DTC bus cycle is initiated.
