Watchdog Handling
- If the watchdog is enabled, it is feed.
- If watchdog is in window mode, no feeding is done, because timer registers are no accessible.
Device Specific Handling
Connect
- The devices access level is checked first, we need 0x02 for full access.
- If devices access level is not 0x02, user is asked for protection remove by chip erase.
- If CPU can be accessed, hot plugging(attach) is tried, otherwise cold plugging is executed, which puts CPU after BOOT Rom in CPU Park mode.
Reset
- The devices uses normal Cortex-M reset, but special communication with BOOT Rom is done afterwards to put CPU in CPU park mode.
Attach
Attach is supported if device is not secured.
This is called hot plugging by Microchip.
