6. Bus Controller
6.4.3
Table 6.4 shows the data buses used, and the 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.

Notes: 1. Undetermined data means that unpredictable data is output.
6.4.4
The initial state of each area is basic bus interface, three-state access space. The initial bus width is
selected according to the operating mode. The bus specifications described here cover basic items
only, and the following sections should be referred to for further details: 6.4, Basic Bus Interface,
6.5, DRAM Interface, 6.8, Burst ROM Interface.
Area 0: When area 0 external space is accessed, the CS
Either basic bus interface or burst ROM interface can be selected for area 0.
The size of area 0 is 128 kbytes in modes 1 and 2, and 2 Mbytes in modes 3 and 4.
Areas 1 and 6: When area 1 and 6 external space is accessed, the CS
respectively can be output.
Only the basic bus interface can be used for areas 1 and 6.
