External Warm Reset to AM335x

External warm reset can only be used as input only to AM335x or output only to reset other devices as written in second last line of  section 8.1.1.7.4.1 (External Warm Reset) of TRM of AM335x. But in in the next section figure shows that it can be implemented in both style at same time and same approach is also followed in EVK and Beagle Bone. Is there any problem in my understanding?

    Hello,

    Although the pin is implemented as bi-directional pin, our latest recommendation is to use the pin as input only or output only due to the reason described in the section 8.1.1.7.4.1 in the TRM. The warm reset circuit will be implemented to follow this recommendation in future reference boards.
