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.
