FUNCTIONAL DESCRIPTION
FUNCTIONAL INTERNAL BLOCK DESCRIPTION
When the Window Watchdog function is selected, the
timer cannot be cleared during the Closed Window time,
which is 50% of the total watchdog period. When the
watchdog is cleared, the timer is reset and starts a new time-
out period. If the watchdog is not cleared during the Open
Window time, the RST will become active (LOW) for a time
determined by the RC components of the RT timer plus
10 ms.
