9. AC Test Conditions:
Input Pulse Voltages: 0.3 V_CC to 0.7 V_CC
Input rise and fall times: ≤ 10 ns
Input and output reference voltages: 0.5 V_CC
Output load: current source I_{OL max}/I_{OH max}; C_L = 30 pF
10. This parameter is tested initially and after a design or process change that affects the parameter.

11. t_PUR and t_PUW are the delays required from the time V_CC is stable at the operating voltage until the specified operation can be initiated.
12. t_WC is the time from the rising edge of CS after a valid write sequence to the end of the internal write cycle.
