The AVR910 programmer type accepts the following extended parameter:
@table @code
@item @samp{devcode=VALUE}
Override the device code selection by using @var{VALUE}
as the device code.
The programmer is not queried for the list of supported
device codes, and the specified @var{VALUE}
is not verified but used directly within the
@code{T} command sent to the programmer.
@var{VALUE} can be specified using the conventional number notation of the
C programming language.
