Are you able to confirm this? And is it the same way on other VSMs?
I've read all VSMs with M0 low. On Mr Challenger, it doesn't look to me like the data is valid until after M0 goes low, but I'm looking at exported data- I didn't save a Logic capture for some reason. I'll set it up again and check.
