NOTE:
(1) This parameter is tested initially and after a design or process change that affects the parameter.
(2) t_PUR and t_PUW are the delays required from the time V_CC is stable until the specified operation can be initiated.
(3) The input levels and timing reference points are shown in the “AC Test Conditions” table.
