Contradictory requirements for result signal stability

Created by: moimfeld

Hi @Silabs-ArjanB

The lines below seem to contradict each other. First it says, all result signals except data must be stable (data must only be stable if we is not 0 during the result transaction) and in line 892 it says the result signals should remain stable, which implies that all result signals (including data) should remain stable.

One could remove the second sentence of line 892 to resolve this contradiction.

Additionally, one could remove the stability condition for the ecsdata signal, if the corresponding ecswe field is low.

Let me know what you think. I can also create a PR if you agree with these changes.
