# three bits of that byte are used on the atmega168, avrdude gets
|

|
# confused if you specify 1's for the higher bits, see:

|
||
|
|
# unlock the bootloader section) and 0xcf instead of 0x0f (to
|
||
|
|
# lock it), but since the high two bits of the lock byte are
|
||
|
|
# unused, avrdude would get confused.
