:) In the "set device" command, what is the distinction between a device
:) that supports full parallel mode vs pseudo parallel mode - the
:) 'parmode' parameter to the "set device" command (buf[4] in avrdude)?
:) Vales of 'yes' and 'no' don't seem to be sufficent to describe the
:) parallel programming capabilities. What is "psuedo" parallel
:) programming support mean?
My interpretation is that the psuedo mode is for the 8-pin avrs which
don't have enough pins for full parallel programming, thus they use a
hiv serial programming (not to be confused with spi ISP). Section
3.7.2.2 of the stk500 user guide seems to discuss this briefly.
I think that parmode (buf[4]) is only meaningful if progtype (buf[3])
is set to one.
