Table 6.4 shows the data buses used and valid strobes for the access spaces.
In a read, the RD signal is valid for both the upper and the lower half of the data bus. In a write,
the HWR signal is valid for the upper half of the data bus, and the LWR signal for the lower half.

8-Bit, 2-State Access Space: Figure 6.11 shows the bus timing for an 8-bit, 2-state access space.
When an 8-bit access space is accessed, the upper half (D15 to D8) of the data bus is used.
