Note 1: Production tested at T
Note 2: Guaranteed by design.
Note 3: In this setting the watchdog timer is inactive and startup delay ends when WDI sees its first level transition. See the Selecting
Note 4: After power-up, or a setting change, there is an internal setup time during which WDI is ignored.
