MSP430FR2476: Security violation (BOR)

Tool/software:

Hi team,

My customer tested enter/exit of LPM4.5 multiple time. Sometime, unexpected reset by security violation occurred when interrupt happens while exiting LMP4.5.

1. What is condition to trigger security violation(BOR)?
2. What should they check to prevent unexpected security violation while using LMP4.5?

Best regards,

Shota Mago
