14.3.1 8-bit Address Mode
2010-09-06 - d0001_Rev1.00
is read from the EBI_AD bus. When a write operation is requested, the address and subsequently the
write data are transferred onto the EBI_AD bus as the EBI_WEn pin is activated. The detailed operation
in the supported modes is presented in the following sections.
Figure 14.1. EBI Overview
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. Read and write signals in 8-bit mode are shown in
Figure 14.2 (p. 133) and Figure 14.3 (p. 133) respectively.
