Latest Updated:05/27/2013

Question:

What is the pin level when the open drain control register (ODR) is 1 and set to NMOS open drain output?

Answer:

When open drain output is set (ODR = 1 and DDR = 1), the output of the corresponding pin is low at DR = 0 and Hi-Z at DR = 1.
When pulled up externally, the pin is high level at DR = 1.
