7.4.9
Normal Transfer Mode (Cycle Steal Mode): Figure 7.15 shows an example of transfer when
TEND 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, word, or longword has been transferred, the bus is released. While the bus is
released, at least one CPU bus cycle is initiated.
Normal Transfer Mode (Burst Mode): Figure 7.16 shows an example of transfer when TEND
output is enabled, and word-size, normal transfer mode (burst mode) is performed from external
16-bit, 2-state access space to external 16-bit, 2-state access space.
