Analog-to-digital converters (ADC) RM0440
692/2126 RM0440 Rev 4
Bits 27:6 Reserved, must be kept at reset value.
Bit 5 JADSTP: ADC stop of injected conversion command
This bit is set by software to stop and discard an ongoing injected conversion (JADSTP
Command).
It is cleared by hardware when the conversion is effectively discarded and the ADC injected
sequence and triggers can be re-configured. The ADC is then ready to accept a new start of
injected conversions (JADSTART command).
0: No ADC stop injected conversion command ongoing
1: Write 1 to stop injected conversions ongoing. Read 1 means that an ADSTP command is
in progress.
Note: The software is allowed to set JADSTP only when JADSTART=1 and ADDIS=0 (ADC is
enabled and eventually converting an injected conversion and there is no pending
request to disable the ADC)
In Auto-injection mode (JAUTO=1), setting ADSTP bit aborts both regular and injected
conversions (do not use JADSTP)
Bit 4 ADSTP: ADC stop of regular conversion command
This bit is set by software to stop and discard an ongoing regular conversion (ADSTP
Command).
It is cleared by hardware when the conversion is effectively discarded and the ADC regular
sequence and triggers can be re-configured. The ADC is then ready to accept a new start of
regular conversions (ADSTART command).
0: No ADC stop regular conversion command ongoing
1: Write 1 to stop regular conversions ongoing. Read 1 means that an ADSTP command is in
progress.
Note: The software is allowed to set ADSTP only when ADSTART=1 and ADDIS=0 (ADC is
enabled and eventually converting a regular conversion and there is no pending request
to disable the ADC).
In auto-injection mode (JAUTO=1), setting ADSTP bit aborts both regular and injected
conversions (do not use JADSTP).
In dual ADC regular simultaneous mode and interleaved mode, the bit ADSTP of the
master ADC must be used to stop regular conversions. The other ADSTP bit is inactive.
Bit 3 JADSTART: ADC start of injected conversion
This bit is set by software to start ADC conversion of injected channels. Depending on the
configuration bits JEXTEN[1:0], a conversion will start immediately (software trigger
configuration) or once an injected hardware trigger event occurs (hardware trigger
configuration).
It is cleared by hardware:
– in single conversion mode when software trigger is selected (JEXTSEL=0x0): at the
assertion of the End of Injected Conversion Sequence (JEOS) flag.
– in all cases: after the execution of the JADSTP command, at the same time that JADSTP is
cleared by hardware.
0: No ADC injected conversion is ongoing.
1: Write 1 to start injected conversions. Read 1 means that the ADC is operating and
eventually converting an injected channel.
Note: The software is allowed to set JADSTART only when ADEN=1 and ADDIS=0 (ADC is
enabled and there is no pending request to disable the ADC).
In auto-injection mode (JAUTO=1), regular and auto-injected conversions are started by
setting bit ADSTART (JADSTART must be kept cleared)
