I don't believe you need "powered_on_to_enable" here. The docs for
"powered_on_to_enable" say:
* This doesn't normally need to be set if timings are already met by
* prepare_to_enable or enable.
In this case "enable" is 250 ms, which subsumes the 200 ms
"powered_on_to_enable".
Can you confirm and then re-post without the "powered_on_to_enable" setting?
Thanks!
