Conversion Modes
There is software programmable selection between performing single or continuous conversion on a
single channel or multiple channels.

MCU Operating Modes
•
Stop Mode
Entering Stop Mode aborts any conversion sequence in progress and if a sequence was aborted
restarts it after exiting stop mode. This has the same effect/consequences as starting a conversion
sequence with write to ATDCTL5. So after exiting from stop mode with a previously aborted
sequence all flags are cleared etc.

Wait Mode
ADC12B12C behaves same in Run and Wait Mode. For reduced power consumption continuous
conversions should be aborted before entering Wait mode.

Freeze Mode
In Freeze Mode the ADC12B12C will either continue or finish or stop converting according to the
FRZ1 and FRZ0 bits. This is useful for debugging and emulation.
