Hi there, 

I have a question about ADUCM322i BM pin.

http://www.analog.com/media/en/technical-documentation/data-sheets/ADuCM322i.pdf 

According to datasheet,it says: 

Boot Mode (BM). This ball determines the start-up sequence after every reset.

Pull-up is enabled at power-up.

Does this mean user does not need to use external pull up?

Since the figure 43, pull up is implemented, so I just want to make sure the proper BM pin setting.
