I looked at that, but I have two inputs.  I don't see any way to use that
hardware for more than one channel, at least not without adding external

If A/D-Converter and AnaComp are unused, you can use the ADC's input MUX and connect it's output with an AC input. The AC can then be used as input for InCapt of T1. So you can measure up to 7 lines in time slice mode (ICP, ADC0-ADC5).
