Notes:
1. V CC must be applied simultaneously with or before V PP and removed simultaneously with or after V PP .
2. This parameter is only sampled, and is not 100% tested. Output float is defined as the point where data is no longer driven.
See timing diagram.
3. Program pulse width tolerance is 100μsec ? ± ? 5%.
