RTX51: INTERRUPTS STOP WORKING

Information in this article applies to:

• RTX51 Version 5.10b

QUESTION

I'm using RTX51 Full and have modified the priority of the system timer interrupt. Now, I'm having problems with interrupt service routines. A few seconds after starting the system, it stops generating interrupts. What's going on?

ANSWER

The RTX51 system interrupt must run at the lowest possible interrupt priority. Otherwise, the interrupt system of the device might get confused. Therefore, you should not change the priority level of the RTX51 System Timer Interrupt.
