FlexBus AC Timing Characteristics
The following timing numbers indicate when data is latched or driven onto the external bus, relative to the system clock.

1
The frequency of operation is the same as the PCI frequency of operation. The MCF548X supports a single
external reference clock (CLKIN). This signal defines the frequency of operation for FlexBus and PCI.
2
Max cycle rate is determined by CLKIN and how the user has the system PLL configured.
3
Timing for chip selects only applies to the FBCS[5:0] signals. Please see
Section 9.2, “DDR SDRAM AC Timing
Characteristics
” for SDCS[3:0] timing.
4
The FlexBus supports programming an extension of the address hold. Please consult the MCF548X
specification manual for more information.
5
These specs are used when the PCIAD[31:0] signals are configured as 32-bit, non-muxed FlexBus address
signals.
