ADMOD0 to 10. In fixed-channel continuous conversion mode, the AD converter
repeatedly converts a single selected channel. When the conversion process is
completed, ADMOD0<EOCF> is set to 1. ADMOD0<ADBF> is not cleared to 0 and
remains set.
<ITM0>=0, an interrupt is generated after each conversion. When <ITM0>=1, an
interrupt is generated after every four conversions.
Channel scan continuous conversion mode
ADMOD0 to 11. In channel scan continuous conversion mode, the AD converter
repeatedly converts a selected group of channels. When a single conversion sequence is
completed, ADMOD0<EOCF> is set to 1 and an INTAD interrupt is generated.

ongoing conversion is completed and clears ADMOD0<ADBF> to 0.
IDLE1, or STOP) causes the AD converter to be immediately disabled, even if a
conversion is in progress. Once the TMP91CW40 exits the HALT mode, the AD
converter restarts a conversion sequence in fixed-channel continuous conversion or
channel scan continuous conversion mode, but remains inactive in fixed-channel single
conversion or channel scan single conversion mode.
