Watchdog
To supervise the operation of 2
m-processors watchdog logic for two input signals is
integrated. The logic expects at each WD1 and WD2 rectangular signals with 10 ms high
and 10 ms low time. Deviations from the expected time are counted as errors and
influence the output signals.
A digital filter suppresses noise or pulses below 3 clock cycles (typ. 3 ms).
The detection ciruit is described in Figure 12.
After power up and 1or 2 valid watchdog edges the WD logic enables the output Drivers.

are present; WD1 and WD2 start with logic Low
