RM57L843: N2HET BR instruction not set HETFLG bit

Part Number: RM57L843

Tool/software:

Hi,

I wrote a HET code where I branch using BR instruction when Carry flag is set (generated by add/sub during wraparound) with IRQ turned on. However, I noticed that the HETFLG bit is not being set when the condition is satisfied. When I run it on the simulation, I see that the HETFLG is set correctly but not when I execute it on the actual hardware. Ant pointers on what I could be missing?

Thanks,

Ravi
