•
To minimize the number of IC pins required for the external memory connection, the NOR flash
memory controller supports multiplexed address and data memory devices without adding logic
externally.
•
Multiplexing mode can be selected through the GPMC.
[9] MUXADDDATA bit (i = 0
to 7).
•
Asynchronous page mode is not supported for multiplexed address and data devices.
