tISU
Input register setup time: the amount of time the synchronous input of
the flip flop must be stable before the active clock edge
3.12
tIH
Input register hold time: the amount of time the synchronous input of the
flip flop must be stable after the active clock edge
0
tICLK
Input register clock to Q: the amount of time taken by the flip flop to
output after the active clock edge
1.08
tIRST
Input register reset delay: amount of time between when the flip flop is
“reset”(low) and when Q is consequently “reset” (low)
0.99
tIESU
Input register clock enable setup time: the amount of time “enable” must
be stable before the active clock edge
0.37
