Stop an interrupt for an other interrupt and resume

Joel Soares

Other Parts Discussed in Thread: CONTROLSUITE

Hello,

1 - If an interrupt is running, can it be interrupted by a higher priority interrupt, then resume.
2 - If yes, can it works for interrupts of the same group.
3 - If yes how to enable interrupting of interrupt
4 - If yes how to prohibit interrupting of interrupt

Best regards

1) yes, 2) yes, 3) read, 4) read

Good starting point:

And interrupt manual

Thank you very much for the answer.

I forgot to mention that my question is for the f28m35h52c1 concerto.
Is this also true for the control sub-system of F28M35 ?

Hi Joel

Sorry, I do not know the concerto, so I cannot answer you in details. TI delivers sample code for so called "SW prioritized Interrupts". This is the way you can assign different priorities to interrupts. They do deliver sample code for F28M35x (I saw this in controlSUITE).

This could be a starting point for you, I cannot help you further...
