3.8.5 BSEL2 Jumper The BSEL2 jumper connects the Byte Select 2 signal for High-voltage Programming of
ATmega8, ATmega16, ATmega161, ATmega163, ATmega128, and ATmega323. The
BSEL2 jumper should only be mounted when High-voltage Programming ATmega16,
ATmega161, ATmega163, ATmega128, or ATmega323. When using ATmega8, con-
nect the right BSEL2 pin to PC2 in the target area. See Figure 3-31. For descriptions of
the Byte Select 2 signal, see the programming section of the corresponding parts
datasheet.

3.8.6 PJUMP Jumpers The PJUMP jumpers route the programming pin of AT90S2333, AT90S4433, and
ATmega8 to the programming lines when using High-voltage Programming. The
PJUMP jumpers should only be mounted when using High-voltage Programming on
AT90S2333, AT90S4433, or ATmega8. During debugging, High-voltage Programming
of other parts and ISP programming, these jumpers should not be mounted.
