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.
