reading APPROTECT from code

[OskarM]

Hi,

I want to check if the FW is properly loaded into the chip and the chip is locked. Reading APPROTECT hangs the chip even if SD is not enabled. I assume APPROTECT is somehow protected from writing, but from reading?? SDK12, s132.

Can you provide the code you use to read the APPROTECT ?
