My customer uses ADuC848 and they will use P0.3(pin 46) to output.
So external pull-up resistance is needed as ADuC848 Datasheet.
Q1) Would you let me know your recommended values of external pull-up resistance at P0.3?
They use 3.3V and 5V. (They use 2 kinds of MCUs.)
And if they use Port 0 for accessing external data memory, Port 0 seems to use strong internal pull-ups.
Q2) In this case, would you let me know the value of strong internal pull-up?
Please refer attached ADuC848 Datasheet and let me know your advices.
