Watchdog Timer
The watchdog timer function forces WDS signals active when the ST input is not clocked within the 1
second time-out period. Time-out of the watchdog starts when RST (or RST) becomes inactive. If a high-
to-low transition occurs on the ST input pin prior to time-out, the watchdog timer is reset and begins to
time out again. If the watchdog timer is allowed to time out, the WDS signal is driven active (low) for a
minimum of 130 ms. The ST input can be derived from many microprocessor outputs. The typical signals
used are the microprocessors address signals, data signals, or control signals. When the microprocessor
functions normally, these signals would, as a matter of routine, cause the watchdog to be reset prior to
time-out. To guarantee that the watchdog timer does not time out, a high-to-low transition must occur at
or less than the minimum watchdog time-out of 1 second. A typical circuit example is shown in Figure 6.
