Hello Support,

At the end of STC Selftest and Selfcheck run, does RAM cell contents are destroyed or retained 100%?

Please help,

Thank you.

Regards

Pashan

    Hi Pashan,

    The STC selftest and selfcheck will not destroy RAM and it will be retained 100%.  However, the CPU context will not be retained.  If you are going to run the STC self test during run time (i.e. run certain number of intervals every process loop), then the application will need to manage CPU context.  In particular, CPU core registers, the ARM CP15 and CP13 coprocessor registers, and Debug breakpoiint/watchpoint registers.  This is described in SPNU499 section 8.2.2.
