- Abstract:
- A small circuit board designed to flip the logic of the binary monitors that read back the state of various parameters in the Hardware Watchdog. The desired condition is that the monitors should report all is well as a logic high, vs. a logic low. To report all is well with a logic low is unsafe in that an unpowered circuit, or disconnected cable could be misinterpreted as a good situation.
