  http://forum.adb-engineering.be INTERRUPT ROUTINE BUG IN SX48 FROM UBICOM / SCENIX
  
  
  
  Using the SX48 produced by UBICOM (SCENIX), we find an occasional unpleasant habit of not properly handling the interrupt routine at all times.
  
  
  
  The condition arises when The RTCC hits zero when a call to the beginning of a page is processed.
  
  
  
  The result of this action is that, on leave of the ISR, the interrupt flag will not be reset. A new interrupt is not possible.
  
  
  
  If the program flow of the SX48 depends on external input e.g. Keyboard, RS232.. the outcome is unpredictable.
  
  
  
  QUESTION FOR THE SX48 USERS
  
  
  We would like to know if there are SX48 users who have the same or similar problems with interrupts. We are interested in the ease we can reproduce the error, the impact on systems and if any valid workaround was found.
  
  The level of support by Ubicom (Scenix) and if your project was stopped or redesigned with another processor.
