Hi hitx11,
Your question would be specific to the IC you are using. What is the part number of the IC you are talking about?
If you aren’t able to find the answer in the documentation for the specific part you are using, a very easy way to determine the answer would be to try writing each value to the “port bit” of the output pin you are attempting to toggle and physically measure the pin’s output state with a volt meter. Remember you would need a pull-up resistor correctly connected to the output in question, as explained in the original post topic.
