AO = Analog Output DO = Digital Output ADIO = Analog/Digital Input/Output
1
DIO <6..7> are also pulled down with a 50 k Ω resistor.
2
Also pulled down with a 10 k Ω resistor.
Note: The tolerance on the 50 k Ω pullup and pulldown resistors is very large. Actual value may range between
17 and 100 k Ω .
