DUART interrupt

(1 / 2)


	Do you have a pull up resistor on the DUART interrupt line?  Max
asked me to be sure that this is the case.

RE: DUART interrupt

According to both the schematic and the parts list (both released) the
DUART Interrupt pullup resistor, R88, is, in fact, loaded. So is R49,
the pullup resistor on the DUART DTACK line.

Why do you ask?
