NOTE:
1. If Reset Command (FFh) is written at Ready state, the device goes into Busy for maximum 5us
2. The time to Ready depends on the value of the pull-up resistor tied R/B pin.ting time.
3. To break the sequential read cycle, CE must be held for longer time than tCEH.
4. The time to Ready depends on the value of the pull-up resistor tied R/B pin.
5. Program / Erase Enable Operation : WP high to WE High.
Program / Erase Disable Operation : WP Low to WE High.
