- * Adv Library Interrupt Service Routine
- *
- *  This function is called by a driver's interrupt service routine.
- *  The function disables and re-enables interrupts.
- *
- *  When a microcode idle command is completed, the ADV_DVC_VAR
- *  'idle_cmd_done' field is set to ADV_TRUE.
- *
- *  Note: AdvISR() can be called when interrupts are disabled or even
- *  when there is no hardware interrupt condition present. It will
- *  always check for completed idle commands and microcode requests.
- *  This is an important feature that shouldn't be changed because it
- *  allows commands to be completed from polling mode loops.
- *
- * Return:
- *   ADV_TRUE(1) - interrupt was pending
- *   ADV_FALSE(0) - no interrupt was pending
