 /**
- * Implement an open drain output using a GeneralIO, represented as a
- * GeneralIO.  clr() puts the pin in input mode, simulating open drain and
- * therefore requiring a pull-up on the net.  set() puts the pin in output
- * mode and sinks current by outputting a logic zero.  By definition, the
- * pin wrapped by this component can only be used as an output.
+ * Provide an open drain output as a GeneralIO using a GeneralIO.  set() puts
+ * the pin in high impedance state by selecting the pin input mode.  clr() sets
+ * the pin to sink current to ground by selecting the pin output mode, logic
+ * zero.  Generally, an external pull-up resistor will be used with an open
+ * drain output.
  *
- * TODO: there could be a version of this component that uses the msp430's
- * built-in pull-up resistor...
+ * This pin can only be an open drain output and cannot be reconfigured.
