Field Description
0–6 Reserved
A write of any value has no effect. The read value is always 0.
7
NSTART
This status bit signals that a normal conversion is ongoing. This bit stays high while the
conversion is ongoing (or pending during injection mode).
8
JABORT
This status bit signals that an injected conversion has been aborted. This bit is reset when a
new injected conversion starts.
9–10 Reserved
A write of any value has no effect. The read value is always 0.
11
JSTART
This status bit signals that an injected conversion is ongoing.
12–14 Reserved
A write of any value has no effect. The read value is always 0.
15 Reserved
A write of any value has no effect. The read value is always 0.
16–22
CHADDR[0:6]
Channel under measure address
This status bit signals which channel is under measure.
23–25 Reserved
A write of any value has no effect. The read value is always 0.
26
ACKO
Auto-clock-off enable
This status bit signals if the Auto-clock-off feature is on.
27–28 Reserved
A write of any value has no effect. The read value is always 0.
