Characteristics” for SD_CS[3:0] timing.
The processor drives the data lines during the first clock cycle of the transfer
with the full 32-bit address. This may be ignored by standard connected
devices using non-multiplexed address and data buses. However, some
applications may find this feature beneficial.
The address and data busses are muxed between the FlexBus and SDRAM
controller. At the end of the read and write bus cycles the address signals are
indeterminate.
