I have problems with the ISP. All the pulses are send well. I can see it in my oscilloscope. All times and frequenies are ok.
The chip is ok and works fine in parallel mode. I mean it's not burned.
In the datasheet there is something like RD_INT or READ_INT command but this is command is nowhere. Does anybody knows how can I talk via ISP whih this chip.
Ah, As I send the pulses at MOSI (0-5V) by clocking the SCLK, I see some pulses at the MISO, at the falling SCLK edge but the voltage is (0-1V).
