If you look at the daughterboard code, you'll find similarities between the set_auto_tr() and set_enable() calls. Regarding pin output, the difference is the use of ATR registers versus the normal IO register; for ATR masked pins, the ATR registers have precedence. In other words, if set_auto_tr() is set to true, then set_enable() will have no effect.
