H = High Voltage Level; h = High Voltage Level One Setup Time Prior to the Low−to−High Clock Transition; L = Low
Voltage Level; l = Low Voltage Level One Setup Time Prior to the Low−to−High Clock Transition; NC = No Change,
State Prior to Low−to−High Clock Transition; X = High or Low Voltage Level and Transitions are Acceptable; Z = High
Impedance State; ↑ = Low−to−High Transition; ↑ = Not a Low−to−High Transition; For I_CC Reasons DO NOT FLOAT
