WebThe first is that the other components on the assembly, even though active, will present a reduced load. This is because there is less current available to interfere with reading and programming the eeprom in-circuit allowing the push-pull driver to be more effective. The second is that the microcontroller (processor), which will normally start ... WebNote: Reading from the EEPROM does not degrade the memory. You can read an EEPROM address as many times as you want. TIP: To extend EEPROM life first read the contents to be written - if it is the same as the value you want to write, then don't write to it! TIP: Each time you write a set of data - read it back to ensure it was written correctly ...
