Giving pullup to the output side

Web• Pull-up / pull-down / keeper (set by PKE, PUE and PES in IOMUXC) Figure 6. Simplified internal structure of the IOMUX for each pin Pins have a three-state logic. If no device is enabled, then the pins are in high impedance state. It means that the output driver is not controlling the state of a connected circuit. WebU2, if installed, allows activating Q2 for extra power delivery ("strong pullup") to the 1-Wire slave. Unless the isolator adds a delay of 100ns or more, this circuit works for standard and overdrive 1-Wire speeds. ... In some cases, one can chose between parts that, without power on the input side, have the output high or low, depending on ...
