14.3.1 Non-multiplexed 8-bit Data, 8-bit Address Mode
In this mode, 8-bit address and 8-bit data is supported. The address is put on the higher 8 bits of the
EBI_AD lines while the data uses the lower 8 bits. This mode is set by programming the MODE field in
the EBI_CTRL register to D8A8. The address space can be extended to 256 MB by using the EBI_A
lines as described in Section 14.3.6 (p. 180) . Read and write signals in 8-bit mode are shown in
Figure 14.2 (p. 176) and Figure 14.3 (p. 176) respectively.
