Note 14:
A signal is Valid if it is above V
IH
or below V
IL
and Invalid if it is between V
IL
and V
IH
. For the purposes of this specification the following conditions apply:
a) All input signals are defined as: V

c) Delay Times are measured from the input signal Valid to the output signal Valid.
d) Setup Times are measured from the data input Valid to the clock input Invalid.
e) Hold Times are measured from the clock signal Valid to the data input Invalid.
f) Pulse widths are measured from V
