Does anyone know what the diode is connected to at the top left hand corner?? The datasheet recommends this method of connection to protect the μcu, which makes sense with high voltage programming potentially damaging the chip. I'm just a little confused as to why its not labelled and what is it supposed to be?
I intended to use 1k Ω for R and 4.7k for R1 - does this make sense? The datasheet allows a lot of leeway for values.
