6.4.3
Table 6-4 shows the data buses used and valid strobes for the access spaces.
In a read, the RD signal is valid without discrimination between the upper and lower halves 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.
