Flash logic signals with other EBI signals on the EBI pins. The EBI pins in
dedicated to the CompactFlash interface as soon as the EBI_CS4A and/or EBI_CS5A field of
the EBI_CSA Register in the Chip Configuration User Interface is set. These pins must not be
used to drive any other memory devices.
The EBI pins in
responding CompactFlash interface is enabled (EBI_CS4A = 1 and/or EBI_CS5A = 1).
