eMIOS Channel Internal Timebase Interference

vusal — Fri, 27 Sep 2024 21:34:54 GMT

Hello,

Does the internal counter have an effect outside of its own channel? For example, if I have two channels (one input and one output) running on their own internal timebase will they interfere with each other? In this diagram it seems like the internal counter feeds back to the Counter bus.

Thanks!

Hi@vusal

Some channels have internal counters, which can be output as Couner_bus_A, Couner_bus_B, Couner_bus_C, Couner_bus_D, Couner_bus_F.

Hi @Senlent ,

Thank you for your message!

Any thoughts on when reading A and B in the IPM mode, FLAG bit doesn't get set and instead I have the OVFL bit?

Thanks!
