#90260 - all or nothing ! Responding to: ???'s previous message |
The answer is simple:
all can happen or nothing. The first state, which was guaranteed is the state after reset was applied and 24 oscillator cycle are gone. If you must support a failure of the external reset circuit, then you must use a derivate with an internal low voltage reset (brown out reset). Also in case, if the clock may fail, you must use a derivate with internal clock watching circuit and asynchronous reset of all port pins. Peter |
