I remember I got bit by this also when I scheduled more conversions
without a timer; pen-up event would not get noticed. I didn't check
the specs to see if there was a way to configure the HW to do
otherwise.

UPDOWN bits in ADCDAT0 and ADCDAT1 are valid only in WAIT4INT mode, it's wrong 
to check them in select callback because ADC is not in WAIT4INT mode.

We do put it in WAIT4INT mode rigtht there though so it looks like we
just need to move that call (well the original doing WAIT4INT | INT_UP)
before we check for pen state.
