Chip Select Lines
1354D–ATARM–08/02
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 external 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
following combinations are possible:

Note:
EBI
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.
