Recovery operations. In a typical operation, the following events can cause a reset:
•
•
•
•
•
When the device is in STOP mode, a Stop Mode Recovery is initiated by either of the
following:
•
•
The VBO circuitry on the device generates the VBO reset when the supply voltage drops
below a minimum safe level.

operating characteristics. The system reset is longer, if the external crystal oscillator is
enabled by the Flash option bits, allowing additional time for oscillator start-up.
Power-On Reset (POR)
Voltage Brownout (VBO)
Watchdog Timer time-out (when configured by the WDT_RES Flash option bit to
initiate a reset).
External RESET pin assertion (when the alternate RESET function is enabled by the
