The EBI provides up to eight chip select lines:
By exchanging address lines for chip select lines, the user can optimize the EBI to suit the exter-
nal memory requirements: more external devices or larger address range for each device.
The selection is controlled by the ALE field in EBI_MCR (Memory Control Register). The follow-
ing combinations are possible:

Note:
Note:
• Chip select lines NCS0 - NCS3 are dedicated to the EBI (not multiplexed).
• Chip select lines CS4 - CS7 are multiplexed with the top four address lines A23 - A20.
A20, A21, A22, A23 (configuration by default)
A20, A21, A22, CS4
A20, A21, CS5, CS4
