Watchdog Handling
- The device has a watchdog WDT.
- The watchdog is fed during flash programming.
Device Specific Handling
Info Flash
The EDMS105N has a key storage (0x01000000 to 0x0100007F)
at the beginning of the Info Flash sector (0x01000000 to 0x01000000) which is NOT readable, only writable.
Any readout of the key storage (0x01000000 to 0x0100007F), will show up 0xFF, instead of the programmed values.
User can read the Info sector (keys are displayed as 0xFF, even if they are programmed).
User can verify the programmed data (when no keys are programmed).
When user programs data into the Info Flash sector with keys included, verify has to be switched off, or it will fail.
Reset
- The devices uses normal Cortex-M reset, no special handling necessary, like described here.
