atmega128

ATMEGA 128 (AVR) is a microcontroller that has been equipped for 4Kbyte in its chip EEPROM. EEPROM is separate from the AVR flash memory, and can be written, read per byte. To be able to access the EEPROM it needs to manage registers and fuse bit. To prevent errors in the writing and reading of EEPROM cultivated power supply that is used quite stable.

 

When reading the EEPROM microcontroller stops during the four clock cycles before doing the next command, and to write EEPROM microcontroller’s clock stopped during the second cycle before doing the next command.
