ADSP-2173 TIMING PARAMETERS
GENERAL NOTES
Use the exact timing information given. Do not attempt to de-
rive parameters from the addition or subtraction of others.
While addition or subtraction would yield meaningful results for
an individual device, the values given in this data sheet reflect
statistical variations and worst cases. Consequently, you cannot
meaningfully add up parameters to derive longer times.
TIMING NOTES
Switching characteristics specify how the processor changes its
signals. You have no control over this timing; it is dependent on
the internal design. Timing requirements apply to signals that
are controlled outside the processor, such as the data input for a
read operation.
Timing requirements guarantee that the processor operates cor-
rectly with another device. Switching characteristics tell you
what the device will do under a given circumstance. Also, use
the switching characteristics to ensure any timing requirement
of a device connected to the processor (such as memory) is
satisfied.
