NOTES:
H = High voltage level
L = Low voltage level
h = High voltage level one set-up time prior to
Low to High ACLKin transition
l = Low voltage level one set-up time prior to
Low to High ACLKin transition
° = Low to High transition
Z = High impedance (off) state
H* = Goes to level of pull-up voltage
X = Don’t care
O = Output
