Bus Operation
16 bits. SIZ0 and SIZ1 indicate that a word remains to be transferred; A0 and A1 indicate
that the word corresponds to an offset of two from the base address. The multiplexer follows
the pattern corresponding to this configuration of the size and address signals and places
the two least significant bytes of the long word on the word portion of the bus (D16–D31).
The bus cycle transfers the remaining bytes to the word-size port. Figure 4-5 shows the tim-
ing of the bus transfer signals for this operation.
