There is no automatic gating control to ensure that internal weak pull-up or pull-down resistors on a pad are disconnected whenever pad is configured as output. If a pad is always configured in output mode, it is recommended for user software to disable any internal pull resistor tied to it to avoid unnecessary consumption.
Table 18-6 describes the software controls available for pad internal pull-up and pull-down resistors in the control module pad configuration registers.
