Signal Names
In this section, some pins of the ATmega640/1280/1281/2560/2561 are referenced by signal
names describing their functionality during parallel programming, see
9. Pins not 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 29-1. Parallel Programming
