ECC RAM
In order to prevent errors when reading first time, the DLL initializes the first 24Kb of RAM starting at 0x2000 0000.
Watchdog Handling
- The device does have 2 watchdogs.
- The watchdogs are fed during flash programming.
Device Specific Handling
Connect
- On Connect, protection level is checked. For further information regarding this, please click here.
Reset
- The device uses normal Cortex-M reset, no special handling necessary, like described here.
