After a write operation, if no other access (read or write) is pending, the data bus keeps its previous value.
See Section 7.1.3.3.9.10.
7.1.3.3.10.1.1.5 Asynchronous Multiple (Page) Write Operation on an Address/Data-Multiplexed Device
Write multiple (page) access in asynchronous mode is not supported for address/data-multiplexed
devices. If GPMC_CONFIG1_i[28] WRITEMULTIPLE is enabled (1) with GPMC_CONFIG1_i[27]
WRITETYPE as asynchronous (0), the GPMC processes single asynchronous accesses.
For accesses on non-multiplexed devices, see Section 7.1.3.3.10.3.
7.1.3.3.10.1.2 Access on Address/Address/Data (AAD) Multiplexed Devices
7.1.3.3.10.1.2.1 Asynchronous Single Read Operation on an AAD-Multiplexed Device
Figure 7-15 shows an asynchronous single read operation on an AAD-multiplexed device.
