Figure 5-7 shows a word write to an 8-bit bus port. Like the preceding example, this
example requires two bus cycles. Each bus cycle transfers a single byte. SIZ1 and SIZ0
for the first cycle specify two bytes; for the second cycle, one byte. Figure 5-8 shows the
associated bus transfer signal timing.
