Figure 4-12 and Figure 4-13 show an example of a long-word transfer to an odd address in
long-word-organized memory. In this example, a long-word access is attempted beginning
at the least significant byte of a long-word-organized memory. Only one byte can be trans-
ferred in the first bus cycle. The second bus cycle then consists of a three-byte access to a
long-word boundary. Since the memory is long-word organized, no further bus cycles are
necessary.
