DIO<6..7> are also pulled down with a 50 kΩ resistor.
AI = Analog Input DIO = Digital Input/Output pu = pull up
AO = Analog Output DO = Digital Output ADIO = Analog/Digital Input/Output
2
Also pulled down with a 10 kΩ resistor.
The tolerance onthe 50 kΩpull-up and pull-downresistors is verylarge. Actualvalue mayrange between 17 kΩ and 100 kΩ.
