With all device types, the GPMC does not drive unnecessary address lines. They stay at their reset
value of 00.
Address mapping supports address/data-multiplexed 16-bit wide devices:
• The NOR flash memory controller still supports non-multiplexed address and data memory devices.
• Multiplexing mode can be selected through the GPMC_CONFIG1_i[9-8] MUXADDDATA bit field (i =
0 to 7).
• Asynchronous page mode is not supported for multiplexed address and data devices.
