Hi all,

I set a NMI iand enable the external and internal exception by setting register in TSR.GEE.

I also hook NMI to an interrupt c code.

Now, i want to test if my setup works, how to I trigger an exception?

is it possible by doing this in dsp c code side?

Hi,

Take a look at the Chip Interrupt Controller User Guide: Section 2.4.3 NMI Event Generation to Core.

Hi Yordan,

Thank for the information.

Do you know how to set program that register in DSP code?

or do you have an example?

Thank you.

Hi,

This is a simple write to the register base address: 0x02620200.

There is the HWREG(), HW_WR_REG(), HW_RD_REG, etc.. macros in pdk. You can check any driver for reference. Also see the hw_types.h, where all of these are defined.

Best Regards,

Yordan
