TMS570 Interrupts and abort nesting

Henry Abril1

Hi,

Could you please help me to clarify the following items/assumptions:

1. Is the execution of an abort handler interruptible by:

a. a FIQ? (I assume no)

b. an IRQ? (I assume no)

2. Is the execution of an FIQ interruptible by:

a. an abort?

3. Is the execution of an IRQ interruptible by:

a. an abort? (I assume yes)

Thank you,

Henry

Henry,

Please have a look to the following ARM documentation:

Hi Jean-Marc,

The info is precisely what I was looking for, but seems like it is not applying for my device:

Applies to: ARM1020/22E, ARM1026EJ-S, ARM1136, ARM720T, ARM7EJ-S, ARM7TDMI, ARM7TDMI-S, ARM920/922T,ARM926EJ-S, ARM940T, ARM946E-S, ARM966E-S, ARM9TDMI

Could you confirm that the information there applies to the TMS570 too? (CortexR4-F).

Thank you,

Henry
