Section 6 Bus Controller
8-Bit 3-State Access Space: Figure 6.6 shows the bus timing for an 8-bit 3-state access space.
When an 8-bit access space is accessed, the upper half (D15 to D8) of the data bus is used.
Wait states can be inserted.
These group have no lower data bus (D7 to D0) pins or LWR pin. In these group, the upper data
bus (D15 to D8) pins are designated D7 to D0, and the HWR signal pin is designated WR.
