Data Protection
The following circuitry has been included to prevent
inadvertent writes:
– The WEL bit must be set to allow write operations.
– The proper clock count and bit sequence is required
prior to the stop bit in order to start a nonvolatile write
cycle.
– A three step sequence is required before writing into
the control register to change watchdog timer or
block lock settings.
– The WP pin, when held HIGH, prevents all writes to
the array and the control register.
– Communication to the device is inhibited as a result
of a low voltage condition (V
CC
< V
TRIP
)any in-
progress communication is terminated.
– Block lock bits can protect sections of the memory
array from write operations.
