2.4.5.3 Operation Modes Description
Default Mode (OPM0)
Mode OPM0 is the default operating mode of the device after power up or after a rest event. In OPM0, the device
is in Disabled State.
The following exhaustive list of events bring the device in OPM0 Mode:
• Occurrence of a Reset Event.
• Bit SCTRL.CLRS set while the device was in OPM1.
Error Mode (OPM1)
Mode OPM1 is the operating mode of the device after an Event Class B.
The following exhaustive list of events bring the device in OPM1 Mode:
• Occurrence of an Event Class B.
In OPM1, when bit SCTRL.CLRS is set via the corresponding SPI command, the device shall normally jump to
OPM0. However, in case the conditions for an Event Class B are met at that moment, no state transition occurs
and the device stays in OPM1. The operation of bit SCTRL.CLRS on the secondary sticky bits works normally.
In OPM1, when a valid ENTER_CMODE command is received, the device shall normally jump to OPM2.
However, in case the conditions for an Event Class B are met at that moment, no state transition occurs and the
device stays in OPM1 for the duration of the event. The state transition to OPM2 is executed as soon as the
conditions leading to the Event Class B disappear.It shall be noted that no LMI error notification is issued.
Configuration Mode (OPM2)
Configuration Mode is the mode where the configuration of the device can be modified. When OPM2 is active, the
device is in Disabled State.
The following exhaustive list of events bring the device in Configuration Mode:
• Reception of a valid ENTER_CMODE command while Mode OPM0 or OPM1 active.
Configured Mode (OPM3)
Configured Mode is the mode where the device is ready to be enabled. When OPM3 is active, the device is in
Disabled State.
The following exhaustive list of events bring the device in Mode OPM3:
• Reception of a valid EXIT_CMODE command while Mode OPM2 active.
• Event Class A while Mode OPM4 active.
Active Mode (OPM4)
The Active Mode corresponds to the normal operating mode of the device. When OPM4 is active, the device is in
Active State. The following exhaustive list of event bring the device in Active Mode:
