<ul>
<li>
The <code>devicecode</code> parameter is the device code used by the STK500
and is obtained from the software section (<code>avr061.zip</code>) of
Atmel&rsquo;s AVR061 application note available from
<a href="http://www.atmel.com/dyn/resources/prod_documents/doc2525.pdf">http://www.atmel.com/dyn/resources/prod_documents/doc2525.pdf</a>.
</li><li>
Not all memory types will implement all instructions.
</li><li>
AVR Fuse bits and Lock bits are implemented as a type of memory.
</li><li>
Example memory types are: <code>flash</code>, <code>eeprom</code>, <code>fuse</code>,
<code>lfuse</code> (low fuse), <code>hfuse</code> (high fuse), <code>efuse</code>
(extended fuse), <code>signature</code>, <code>calibration</code>, <code>lock</code>.
</li><li>
The memory type specified on the AVRDUDE command line must match one of
the memory types defined for the specified chip.
</li><li>
The <code>pwroff_after_write</code> flag causes AVRDUDE to attempt to power
the device off and back on after an unsuccessful write to the affected
memory area if VCC programmer pins are defined. If VCC pins are not
defined for the programmer, a message indicating that the device needs a
power-cycle is printed out. This flag was added to work around a
problem with the at90s4433/2333&rsquo;s; see the at90s4433 errata at:
<p> <a href="http://www.atmel.com/dyn/resources/prod_documents/doc1280.pdf">http://www.atmel.com/dyn/resources/prod_documents/doc1280.pdf</a>
<p>Parts can also inherit parameters from previously defined parts
using the following syntax. In this case specified integer and
string values override parameter values from the parent part. New
memory definitions are added to the definitions inherited from the
parent.
</p>
</li><li>
The boot loader from application note AVR109 (and thus also the AVR
Butterfly) does not support writing of fuse bits. Writing lock bits
is supported, but is restricted to the boot lock bits (BLBxx). These
are restrictions imposed by the underlying SPM instruction that is used
to program the device from inside the boot loader. Note that programming
the boot lock bits can result in a &ldquo;shoot-into-your-foot&rdquo; scenario as
the only way to unprogram these bits is a chip erase, which will also
erase the boot loader code.
<p>The boot loader implements the &ldquo;chip erase&rdquo; function by erasing the
flash pages of the application section.
</p>
<p>Reading fuse and lock bits is fully supported.
