Hello All

How to change interrupt priority (device TMS320F2837xD) ?

For example I need that CLA_7 ISR interrupts USER12 ISR.

Off cose is posible to activate USER11 interrupt from CLA_7 ISR. But I mean Is there some priority configuration to change the priority of interrupts?

Best regards

Andrii,

There is no way to change the priority in the hardware itself. Prioritization can be done in software by re-enabling interrupts. The following example shows how to do this:

C:\ti\c2000\C2000Ware_<version>\device_support\f2837xd\examples\cpu1\sw_prioritized_interrupts

Also refer to the device specific Technical Reference Manual (TRM) for information on the correct procedure for enabling interrupts, disabling interrupts and nesting interrupts.

Regards
Lori
