This section describes how to parallel program and verify Flash Program memory, EEPROM
Data memory, Memory Lock bits, and Fuse bits in the
ATmega169A/169PA/329A/329PA/3290A/3290PA/649A/649P/6490A/6490P. Pulses are
assumed to be at least 250ns unless otherwise noted.

ATmega169A/169PA/329A/329PA/3290A/3290PA/649A/649P/6490A/6490P are referenced by
signal names describing their functionality during parallel programming, see
page 314
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
