MC9S12G Datasheet, PDF (422/1160 Pages) Freescale Semiconductor, Inc – Ignores external trigger. Performs one conversion sequence and stops.

◁

Analog-to-Digital Converter (ADC10B16CV2)

â¢ Automatic return to low power after conversion sequence

â¢ Automatic compare with interrupt for higher than or less/equal than programmable value

â¢ Programmable sample time.

â¢ Left/right justiï¬ed result data.

â¢ External trigger control.

â¢ Sequence complete interrupt.

â¢ Analog input multiplexer for 8 analog input channels.

â¢ Special conversions for VRH, VRL, (VRL+VRH)/2.

â¢ 1-to-16 conversion sequence lengths.

â¢ Continuous conversion mode.

â¢ Multiple channel scans.

â¢ Conï¬gurable external trigger functionality on any AD channel or any of four additional trigger

inputs. The four additional trigger inputs can be chip external or internal. Refer to device

speciï¬cation for availability and connectivity.

â¢ Conï¬gurable location for channel wrap around (when converting multiple channels in a sequence).

13.1.2 Modes of Operation

13.1.2.1 Conversion Modes

There is software programmable selection between performing single or continuous conversion on a

single channel or multiple channels.

13.1.2.2 MCU Operating Modes

â¢ 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 ï¬ags are cleared etc.

â¢ Wait Mode

ADC10B16C behaves same in Run and Wait Mode. For reduced power consumption continuous

conversions should be aborted before entering Wait mode.

â¢ Freeze Mode

In Freeze Mode the ADC10B16C will either continue or ï¬nish or stop converting according to the

FRZ1 and FRZ0 bits. This is useful for debugging and emulation.
