I suspect that you might have stuck overflow problem. Is it possible???

SCI0 interrupts comes most frequently and SCI1 interrupt in enabled but not used at present. In above configuration, MCU losses the all interrupt handling during the run time of our application. I have checked the value of registers but they are not changed or garbased. Please anybody can show the solution - why MCU losses the all interrupts.
