Details:

I tried to read fuses bits in avrdude, and both lfuse and hfuse are OK under
safemode, but efuse is read as 0.

Reading lfuse:
avrdude: jtagmkII_send(): sending 11 bytes
avrdude: Sent: . [1b] . [0b] . [00] . [0b] . [00] . [00] . [00] . [0e] / [2f]

avrdude: safemode read 3, lfuse value: ff
avrdude: safemode: lfuse reads as FF

Reading hfuse:

Reading efuse:

avrdude: safemode read 1, efuse value: 0
It should be 0xf8 according to the data returned, but avrdude displays 0.
