Data Protection & Power up sequence
The device is designed to offer protection from any involuntary program/erase during power-transitions. An internal voltage detector
disables all functions whenever Vcc is below about 1.1V(1.8V device) or 2V(3.3V device). WP pin provides hardware protection and
is recommended to be kept at VIL during power-up and power-down and recovery time of minimum 10µs is required before internal
circuit gets ready for any command sequences as shown in Figure 18. The two step command sequence for program/erase provides
additional software protection.
