It seemed like a reasonable idea at the time. I'm using it to monitor
the line voltage. You send it a command. It tells you the min input
voltage since the last time you asked. The faster I ask the better
time resolution I get on the duration of glitches.

Thanks for the suggestion. It's a 1 GHz VIA C7 system. It was running
at 250 Hz. I just switched to 100. No change.
These are my opinions, not necessarily my employer's. I hate spam.
