Timing for chip selects only applies to the FB_CS[5:0] signals. Please see
Specifications,”
The FlexBus supports programming an extension of the address hold. Please consult the device reference manual for more
information.
Data Input Setup

Transfer Acknowledge (TA) Input Setup
Transfer Acknowledge (TA) Input Hold
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.
