depends on the programmer itself. See below for a list of programmers
accepting extended parameters.
@item -y
Tells AVRDUDE to use the last four bytes of the connected parts' EEPROM
memory to track the number of times the device has been erased. When
this option is used and the @option{-e} flag is specified to generate a
chip erase, the previous counter will be saved before the chip erase, it
is then incremented, and written back after the erase cycle completes.
Presumably, the device would only be erased just before being
programmed, and thus, this can be utilized to give an indication of how
many erase-rewrite cycles the part has undergone. Since the FLASH
memory can only endure a finite number of erase-rewrite cycles, one can
use this option to track when a part is nearing the limit. The typical
limit for Atmel AVR FLASH is 1000 cycles. Of course, if the
application needs the last four bytes of EEPROM memory, this option
should not be used.
@item -Y @var{cycles}
Instructs AVRDUDE to initialize the erase-rewrite cycle counter residing
at the last four bytes of EEPROM memory to the specified value. If the
application needs the last four bytes of EEPROM memory, this option
should not be used.
