TMS320F28069: Nested Interrupts within different PIE group

Rolando Aguilera

Part Number: TMS320F28069
Other Parts Discussed in Thread: C2000WARE

Hello everyone,

I wonder if the F28069 can handle nested interrupts within a different PIE group.

For example an interrupt from PIE group 8 (I2CINT1A) must have higher priority than SPIRXINTA Interrupt from group 6.

Thanks and regards,

Rolando

    Rolando,

    The interrupt priority is fixed in hardware, however it is possible to implement prioritization of the Interrupts in software.  For details, please see the F2806x Firmware Development Package User's Guide starting on page 135:
