Timing for chip selects only applies to the FB_CS[5:0] signals. Please see
Characteristics” for SD_CS[3:0] timing.
The FlexBus supports programming an extension of the address hold. Please consult the MCF5329 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.
