Tokasa However the doubt stand. On top of datasheett, when I will get into power-optimization for the MCU I may end up having to choose between satasheet the interrupts alive or saving power. The most complex part by design is planned to be the MCU. Hi, thanks for the reply! I had a sync. Any way, take into account that the SNN has been obsolete for 25 years, its not a good idea to even consider that part for a new design.

Following up my previous comment: Post as a guest Name. Looks like an SR is my only choice here, but my brain is just a drop of the ocean.
I would disagree, but I may be missing the picture here. The shortcoming is that I have 4 separate resets, while ideally I would need only one. I want to keep it flexible, both capability and power-usage wise and this requires balance.
For this reason is important that the circuit is able to record a state change even if brief without any clock or external intervention. MCU, comms module and voltage regulation sections. Sourcing it could be really troublesome. Tony EE rocketscientist However the doubt stand. For this to work you need a pull-down resistor on every output. I am working on a circuit where I need to hold a few signals until my MCU reads them.
