serial programming instructions are not very orthoganal, i.e., the
"read fuse bits" instruction on an ATMega103 is an entirely different
opcode and data format from the _same_ instruction for an ATMega163!
Thus, it becomes impossible to have a single instruction encoding
(varying the data) across the chip lines.
This set of changes allows and requires instruction encodings to be
defined on a per-part basis within the configuration file. Hopefully
I've defined the encoding scheme in a general enough way so it is
useful in describing the instruction formats for yet-to-be invented
Atmel chips. I've tried hard to make it match very closely with the
specification in Atmel's data sheets for their parts. It's a little
more verbose than what I initially hoped for, but I've tried to keep
it as concise as I could, while still remaining reasonably flexible.

Add support for reading/writing ATMega163 lock and fuse bits.
Unfortunately, in looking at the specs for other ATMega parts, they
use entirely different instruction formats for these commands. Thus,
these routines won't work for the ATMega103, for example.
Add support for sending raw command bytes via the interactive terminal
interface. This allows one to execute any programming instruction on
the target device, whether or not avrprog supports it explicitly or
not. Thus, one can use this feature to program fuse / lock bits, or
access any other feature of a current or future device that avrprog
does not know how to do.
Add in comments, an experimental instruction format in the
configuration file. If this works out, it would allow supporting new
parts and non-orthoganal instructions across existing parts without
making avrprog code changes.

Due to the bank addressing required, interactive update of the flash
is not supported, though the eeprom can be updated interactively.
Both memories can be programmed via non-interactive mode.
Intel Hex Record type '04' is now generated as required for outputing
memory contents that go beyond 64K.

can tell unambiguously what version a binary out in the field is.
Additionally, display a revision timestamp along with the version
number. This also is intended for aiding in support and is the Unix

do a "cvs co -D timestamp avrprog" and get exactly the source of the
version that is being reported.

First pass at providing feedback via the optionally connected leds. I
don't actually have any of these attached to my programmer, so I can
only guess as whether this is toggling them on and off correctly.
Also, enable and disable the optional 74367 buffer.

Provide hooks to support a buffered programmer, pin 6 is now used to
enable a buffer that can be used to isolate the target system from the
parallel port pins. This is important when programming the target
in-system.
Totally change the way the pin definitions are defined. Actually
set/clear pins based on the way more intuitive pin number, instead of
PPI data register, bit number combination. A table of pin data is
used so that any hardware inversion done by the parallel port is
accounted for, what you set is actually what appears at the pin.
Retain the old method for handling Vcc, however, because the hold
method is much easier to use when setting / retrieving multiple pins
simultaneously.

prompted.
avr.c avr.h fileio.c term.c :
Change the avrpart data structure so that the typedef AVRMEM is
used as an index into an array for the sizes of the memory types
and also for pointers to buffers that represent the chip data for
that memory type. This removes a lot of conditional code of the
form:
switch (memtype) {
case AVR_FLASH :
...
}
Also, re-code avr_read_byte() and avr_write_byte() to properly
handle the flash memory type without having to tell them whether
they should program the high byte or the low byte - figure that
out from the address itself. For flash memory type, these
routines now take the actual byte address instead of the word
address. This _greatly_ simplifies many otherwise simple
operations, such a reading or writing a range of memory, by not
having to worry about whether the address starts on an odd byte
or an even byte.
