Signal Names
In this section, some pins of the ATmega329P/3290P are referenced by signal names describ-
ing their functionality during parallel programming, see
described in the following table are referenced by pin names.
The XA1/XA0 pins determine the action executed when the XTAL1 pin is given a positive pulse.
The bit coding is shown in
When pulsing WR or OE, the command loaded determines the action executed. The different
Commands are shown in
Figure 27-1. Parallel Programming
