It's OK; I found the problem! A bug in my modified touch-API code. I turned off the Vdet circuits and enabled low-consumption mode (both in vca2 register) before starting the SCU and entering WAIT mode, but when I disabled low-consumption mode again in the SCU interrupt, I forgot to also re-enable the Vdet circuits. All solved, and running nicely now. Sorry to have troubled you!
