According to the description of Section 7.3.2 "Error code correction (ECC)" in the RM0456 manual, reading the data at address 0x0BFA1F80 is supposed to generate an NMI interrupt.
However, when I tried to read the data at this address, no NMI interrupt was triggered.
I was also able to read the data at this address normally using Cube Programmer.
The development board used for testing is the ST`s B-U585I-IOT02A.
Why didn't the read operation trigger an NMI interrupt?
