Browse Source 
* jtagmkII.c: Extend the jtagmkII_read_byte() and
jtagmkII_write_byte() methods to handle EEPROM through
debugWire.

* avrpart.h: Implement the "flash instruction" parameter.
* config_gram.y: (Ditto.)
* lexer.l: (Ditto.)
* avrdude.conf.in: (Ditto.)

* avrdude.1: Document the EEPROM access through dW.
* doc/avrdude.texi: (Ditto.)

* tools/get-dw-params.xsl: Extend to extract the flash
instruction field.

fuse, and then power-cycling the target.
While this mode is mainly intented for debugging/emulation, it
also offers limited programming capabilities.
Effectively, the only memory area that can be read or programmed
in this mode is the flash ROM.
Effectively, the only memory areas that can be read or programmed
in this mode are flash ROM and EEPROM.
It is also possible to read out the signature.
All other memory areas cannot be accessed.
