  • If watchdog is in window mode, no feeding is done, because timer registers are no accessible.

Device Specific Handling


  • The device security bit is checked on connect.
  • If device security bit is set, user is asked for protection remove by chip erase.
  • If security bit and chip erase hard lock bit is set, device can't be accessed or programmed any more.

Attach is not supported, because ECC RAM is initialized.
This is called hot plugging by Microchip.
