External Bus Interface integrates circuitry that interfaces to NAND Flash devices.
The NAND Flash logic is driven by the Static Memory Controller on the NCS3 address space.
Programming the EBI_CS3A field in the EBI_CSA Register in the Chip Configuration User Inter-
face to the appropriate value enables the NAND Flash logic. For details on this register, refer to
the Bus Matrix Section. Access to an external NAND Flash device is then made by accessing
the address space reserved to NCS3 (i.e., between 0x4000 0000 and 0x4FFF FFFF).
The NAND Flash Logic drives the read and write command signals of the SMC on the NANDOE
and NANDWE signals when the NCS3 signal is active. NANDOE and NANDWE are invalidated
as soon as the transfer address fails to lie in the NCS3 address space. See Figure
Signal Multiplexing on EBI Pins” on page 153
