Data Protection
3.8
Power-On State
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
set the write enable latch
? After a byte write, page write or STATUS register
The 25XX320 powers on in the following state:
? The device is in low-power Standby mode
(CS = 1 )
? The write enable latch is reset
? SO is in high-impedance state
? A low level on CS is required to enter active state
write, the write enable latch is reset
? CS must be set high after the proper number of
clock cycles to start an internal write cycle
? Access to the array during an internal write cycle
is ignored and programming is continued
