  * Description:
- *   Sets/clears PIN and interrupt triggers.  On return PIN interrupts are
- *   always disabled.
+ *   Attach a pin interrupt handler.  The normal initalization sequence is:
+ *
+ *   1. Call kinetis_pinconfig() to configure the interrupting pin (pin interrupts
+ *      will be disabled.
+ *   2. Call kinetis_pinirqattach() to attach the pin interrupt handling function.
+ *   3. Call kinetis_pinirqenable() to enable interrupts on the pin.
  *
  * Parameters:
  *  - pinset:  Pin configuration
