16.1.2 Modes of Operation
16.1.2.1 Conversion Modes
There is software programmable selection between performing single or continuous conversion on a
single channel or multiple channels.
16.1.2.2 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
ADC12B16C 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 ADC12B16C will either continue or finish or stop converting according to the
FRZ1 and FRZ0 bits. This is useful for debugging and emulation.
