The selection of batch mode in EEPROM provides the advantage of permanently
saving data in the EEPROM to avoid losing them if for example the batteries run
down.
The RAM selection allows more data to be saved and is transmitted more quickly to
the base station. For example, for a list of codes having an average of 20 characters
each, the EEPROM can store about 60 codes while the RAM can store almost 100.
