Preliminary Information

Valid Delay, Float, Setup, and Hold Timings
The following valid delay and float timings for output signals
during functional operation are relative to the rising edge of
the given clock. The maximum valid delay timings are
provided to allow a system designer to determine if setup
times can be met. Likewise, the minimum valid delay timings
are used to analyze hold times.
The setup and hold time requirements for the AMD-640 system
controller input signals presented here must be met by any
device that interfaces with it to assure the proper operation of
the AMD-640 system controller.
Figure 9-2 illustrates the relationship between the rising clock
edge and setup, hold, and valid data timings.
