BSEL2 Jumper
PJUMP Jumpers
Figure 3-30. XTAL1 and OSCSEL Connections
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.
Figure 3-31. BSEL2 Connection for ATmega8
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.
