#179672 - Yes; that was my point - I was agreeing with you! Responding to: ???'s previous message |
The OP was asking about a single chip having 2 watchdogs within it
Richard Erlacher said:
If one watchdog fails, the second one is not likely to fail as well. Andy Neil said:
I'm not sure that holds (or, at least, not so well) if both watchdogs are on the same chip?
Hence I agree with both you and Oliver in recommending a separate watchdog chip. |
