SmartMedia and NAND Flash Support
Figure 14-5. CompactFlash Application Example without I/O mode
The EBI integrates circuitry that interfaces to SmartMedia and NAND Flash devices.
The NAND Flash logic is driven by the Static Memory Controller on the NCS[2] (and/or NCS[3])
address space. Writing to the HMATRIX.SFR6.CS2A (and/or HMATRIX.SFR6.CS3A) bit the
appropriate value enables the NAND Flash logic. Access to an external NAND Flash device is
then made by accessing the address space reserved to NCS[2] (and/or NCS[3]).
The NAND Flash logic drives the read and write command signals of the SMC on the NANDOE
and NANDWE signals when the NCS[2] (and/or NCS[3]) signal is active. NANDOE and
NANDWE are invalidated as soon as the transfer address fails to lie in the NCS[2] (and/or
NCS[3]) address space. See
these waveforms, refer to the SMC Section.
The SmartMedia device is connected the same way as the NAND Flash device.
