SOC (status

upon readback)

OVR_LATCH CONF_CYCLIC_EN DUTY_ON

Device status

Cyclic activity, (idle phase)

Cyclic activity, (duty phase)

Idle (last execution set the override latch)

Not possible

Cyclic activity locked in idle phase after the end of

override: MCU must set CONF_CYCLIC_EN = 0 and

then run a SOC

Fault detected during cyclic activity with override still

ongoing

Not possible

On-demand conversion

Not possible

On-demand conversion interrupting a cyclic one (must

be avoided since results may not be reliable)

Not possible

On-demand conversion after a fault was detected

Not possible

On-demand conversion interrupting a cyclic one. Failure

detected during the on-demand conversion (must be

avoided since results may not be reliable)

The following FSM describes the functionality and the transitions among the different operating modes of the

voltage conversion routine.
