logic signals with other EBI signals on the EBI pins. The EBI pins in
strictly dedicated to the CompactFlash interface as soon as the HMATRIX.SFR6.CS4A and/or
HMATRIX.SFR6.CS5A bits is/are written. These pins must not be used to drive any other mem-
ory devices.
The EBI pins in
responding CompactFlash interface is enabled (CS4A = 1 and/or CS5A = 1).
