#109294 - Parallel programmer Responding to: ???'s previous message |
So if I use a parallell programmer it will be possible to disable latching of the /EA pin. Seems like a long way to go but wery interesting.
Another question: So called hardware conditions to launch the bootloader is /EA=High and PSEN=Low. In datacheets there is no info about properties for the PSEN output. I have to admit that this pin is also unconnected but as it is an output with normal operation high level and open drain i think it should cause any problems. Is this correct? / Kjell |
