NOTE
MSR[JSTART] is automatically set when the injected conversion starts. At
the same time MCR[JSTART] is reset, allowing the software to program a
new start of conversion.
The JCMR registers do not change their values.

Field Description
NSTART This status bit is used to signal that a Normal conversion is ongoing.
JABORT This status bit is used to signal that an Injected conversion has been aborted. This bit is reset when
a new injected conversion starts.
JSTART This status bit is used to signal that an Injected conversion is ongoing.
CTUSTART This status bit is used to signal that a CTU conversion is ongoing.
CHADDR Current conversion channel address
This status field indicates current conversion channel address.
ACKO Auto-clock-off enable
This status bit is used to signal if the Auto-clock-off feature is on.
ADCSTATUS The value of this parameter depends on ADC status:
000 IDLE
001 Power-down
010 Wait state
011 Reserved
100 Sample
101 Reserved
110 Conversion
