Write Protection
The following circuitry has been included to prevent
inadvertent nonvolatile writes:
— The internal Write Enable latch is reset upon
power-up.
— A reset sequence must be issued to set the internal
write enable latch before starting a write sequence.
— A special “start nonvolatile write” command
sequence is required to start a nonvolatile write
cycle.
— The internal Write Enable latch is reset automatically
at the end of a nonvolatile write cycle.
— The internal Write Enable latch is reset and remains
reset as long as the
WP
pin is LOW, which blocks all
nonvolatile write cycles.
