RTX51 TINY: INTERRUPTS STOP WORKING


Information in this article applies to:

  • C51 Version 5.50a
  • C51 Version 6.10a

QUESTION

I'm using RTX51 Tiny 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.
