The following protection has been implemented to
prevent inadvertent writes to the array:
• The write enable latch is reset on power-up
• A WRITE ENABLE instruction must be issued to
• After a byte write, page write or Status register
• CS must be set high after the proper number of
• Access to the array during an internal write cycle

The 25XX320 powers on in the following state:
• The device is in low-power Standby mode
• The write enable latch is reset
• SO is in high-impedance state
• A low level on CS is required to enter active state
