8.4.3 Address Transfer Attribute Signals
During the address transfer, the address is placed on the address signals, A[0–31]. The bus
master provides other signals that characterize the address transfer—transfer type
(TT[0–4]), transfer code (TC[0–2]), transfer size (TSIZ[0–3]), and transfer burst (TBST)
signals. These signals are discussed in the following sections.
8.4.3.1 Transfer Type Signal (TT[0–4]) Encoding
The transfer type signals define the nature of the transfer requested. They indicate whether
the operation is an address-only transaction or whether both address and data are to be
transferred. Table 8-2 describes the MPC8280's action as master, slave, and snooper.
