Read/Write signals
Multiplexing of CompactFlash signals on EBI pins
In I/O mode and True IDE mode, the CompactFlash logic drives the read command signals of
the SMC on CFNIORD signal, while the CFNOE and CFNWE signals are deactivated. Likewise,
in common memory mode and attribute memory mode, the SMC signals are driven on the
CFNOE and CFNWE signals, while the CFNIORD is deactivated.
onstrates a schematic representation of this logic.
Attribute memory mode, common memory mode and I/O mode are supported by writing the
address setup and hold time on the NCS[4] (and/or NCS[5]) chip select to the appropriate val-
ues. For details on these signal waveforms, please refer to the section: Setup and Hold Cycles
of the SMC Section.

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).
