I having some issues with a few devices that I believe that some security bits got set and are preventing the device from operating correctly. The issue is that the SNVS_HPRTCLR register doesn't increment anymore. This code has worked for years and it stopped one day. I do see that the PGD bit in the SNVS_LPSR is set. There are probably others as well. I believe something happened where the chip thought there was some sort of tampering going on and shut some stuff off. Also this problem is only happening on a couple of my devices. The rest work just fine.
