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 tim-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 10ms.
