Timing for chip selects only applies to the FB_CS[5:0] signals. Please see Section 5.7, "SDRAM BUS” for SD_CS[1:0]
timing.
The FlexBus supports programming an extension of the address hold. Please consult the device reference manual for
more information.
These specs are used when the A[23:0] signals are configured as 23-bit, non-muxed FlexBus address signals.
