MASTER ADC
SLAVE ADC
If DISCEN=1, each "n" simultaneous conversions ("n" is defined by DISCNUM) of the
regular sequence require a regular trigger event to occur.
In this mode, injected conversions are supported. When injection is done (either on master
or on slave), both the master and the slave regular conversions are aborted and the
sequence is restarted from the master (see
ADC1 (master)
ADC2 (slave)
Legend:
Sampling
Alternate trigger mode
This mode is selected by programming bits DUAL[4:0] = 01001.
This mode can be started only on an injected group. The source of external trigger comes
from the injected group multiplexer of the master ADC.
This mode is only possible when selecting hardware triggers: JEXTEN must not be 0x0.
Injected discontinuous mode disabled (JDISCEN=0 for both ADC)
