2.3.4 Write Protection Memory (SLE 4432 and SLE 4442)
The execution of this command contains a comparison of the entered data byte with the assigned
byte in the EEPROM. In case of identity the protection bit is written thus making the data information
unchangeable. If the data comparison results in data differences writing of the protection bit will be
suppressed. Execution times and required clock pulses see UPDATE MAIN MEMORY.
