... This can be useful in protecting the memory from inadvertent write cycles that may occur due to uncontrolled bus conditions. The M28C16 is shipped as standard in the ”unpro- tected” state meaning that the memory contents can be changed as required by the user. After the Software Data Protection enable algorithm is is- sued, the device enters the ” ...
