The PJUMP jumpers route the programming pin to the programming lines when using high-voltage programming of:
-
AT90S2333
-
AT90S4433
-
ATmega48(P)
-
ATmega8
-
ATmega88(P)
-
ATmega168(P)
-
ATmega328P
-
ATtiny48
-
ATtiny88
The PJUMP jumpers should be mounted in the "horizontal" direction, i.e. the same direction as e.g. the BSEL2 jumper.
Note:
The PJUMP jumpers should only be mounted when using high-voltage programming of these devices. During debugging, high-voltage programming of other parts and ISP programming, these jumpers should not be mounted.
