Flash logic signals with other EBI signals on the EBI pins. The EBI pins in
dedicated to the CompactFlash interface as soon as the EBI0_CS4A and/or EBI0_CS5A field of
the EBI0_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
corresponding CompactFlash interface is enabled (EBI0_CS4A = 1 and/or EBI0_CS5A = 1).
