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
– A three step sequence is required before writing into
– The WP pin, when held HIGH, prevents all writes to
– Communication to the device is inhibited as a result
– Block lock bits can protect sections of the memory
prior to the stop bit in order to start a nonvolatile
write cycle.
