NAND Flash/ SmartMedia Support
Figure 17-5. CompactFlash Application Example
The EBI integrates circuitry that interfaces to NAND Flash/SmartMedia devices.
The NAND Flash/SmartMedia logic is driven by the Static Memory Controller on the NCS3
address space. Programming the CS3A field in the Chip Select Assignment Register to the
appropriate value enables the NAND Flash/SmartMedia logic
Select Assignment Register” on page 152.)
device is then made by accessing the address space reserved to NCS3 (i.e., between 0x4000
0000 and 0x4FFF FFFF).
The NAND Flash/SmartMedia Logic drives the read and write command signals of the SMC on
the SMOE and SMWE signals when the NCS3 signal is active. SMOE and SMWE are invali-
dated as soon as the transfer address fails to lie in the NCS3 address space. For details on
these waveforms, refer to the Static Memory Controller
The SMWE and SMOE signals are multiplexed with BFRDY and BFBAA signals of the Burst
Flash Controller. This multiplexing is controlled in the MUX logic part of the EBI by the CS3A
field of the Chip Select Assignment Register
