we use the ADuC848 microcontroller in some equipments that are in full production
for at least four years. Now some of the equipments have shown some malfunction
(for example code restart) related to moisture.
We use the internal Power-on circuit only, so the RESET pin is tied to ground with
a resistor. I know that the pin is described as INPUT, but, because I don't know the
internal circuitry, I wat to ask you if there is a lower limit for this resistor value.
Can someone help me?
