SequencerOff
rw
0
Controls the automatic Sequencer (see section 4.2 ):
0 → Operating mode as selected with Mode bits in
RegOpMode is automatically reached with the Sequence
1 → Mode is forced by the user
6
ListenOn
rw
0
Enables Listen mode, should be enabled whilst in
Standby mode:
0 → Off (see section 4.3)
1 → On
5
ListenAbort
w
0
Aborts Listen mode when set together with ListenOn=0
See section 4.3.4 for details
Always reads 0.
