+/**
+ * Provide an open drain output with internal pull-up.
+ *
+ * Works only for MSP430 processor ports having internal pull up/down resistors.
+ * Since a low value is asserted by using the pull-down resistor instead of the
+ * pull-up resistor, the slew rate of the net might in some cases be too slow.
+ *
+ * This pin can only be an open drain output and cannot be reconfigured.
