Initialize TCM and SRAM contents only after a destructive reset (e.g. PoR reset). SRAM retains content during functional reset through a hardware mechanism, therefore accesses do not cause content corruption errors.

Initialize TCM and SRAM contents only after a destructive reset (e.g. PoR). SRAM on this device retains content during functional reset (e.g. watchdog expiring) through a hardware mechanism, therefore accesses do not cause content corruption errors.
