Write multiple (page) access in asynchronous mode is not supported for AAD-multiplexed devices.
If the GPMC_CONFIG1_i[28] WRITEMULTIPLE bit is enabled (0x1) with the GPMC_CONFIG1_i[27] WRITETYPE bit as asynchronous (0x0), the GPMC processes single asynchronous accesses.
For accesses on non-multiplexed devices, see Section 12.3.4.4.9.3, Asynchronous and Synchronous Accessed in non-multiplexed Mode.
