C. Guaranteed by design over temperature limits.
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
Selecting
Device Timing
for more information.
Note 4:
After power-up, or a setting change, there is an internal setup time during which WDI is ignored.
